Options may be exercised (which may be based on performance criteria), any
vesting acceleration or waiver of forfeiture restrictions, and any restriction

thereto, based in each case on such factors as the Administrator, in its sole
discretion, shall determine;

            (vi) to reduce the exercise price of any Option to the then current

Option shall have declined since the date the Option was granted;

            (vii)  to institute an Option Exchange Program;

            (viii)  to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan;

electing to have the Company withhold from the Shares to be issued upon exercise
of an Option that number of Shares having a Fair Market Value equal to the
amount required to be withheld. The Fair Market Value of the Shares to be
withheld shall be determined on the date that the amount of tax to be withheld
is to be determined. All elections by an Optionee to have Shares withheld for
this purpose

                                      -4-
<PAGE>

shall be made in such form and under such conditions as the Administrator may
deem necessary or advisable;

            (xii) to authorize any person to execute on behalf of the Company

the Administrator;

            (xiii)  to make all other determinations deemed necessary or
advisable for administering the Plan.

        (c) Effect of Administrator's Decision.  The Administrator's decisions,
            ----------------------------------
determinations and interpretations shall be final and binding on all Optionees
and any other holders of Options.

        -----------
however, that notwithstanding anything to the contrary contained in the Plan,
Options may not be granted to Officers and Directors.

    6.  Limitation.  Neither the Plan nor any Option shall confer upon an
        ----------
Optionee any right with respect to continuing the Optionee's relationship as a
Service Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

    7.  Term of Plan.  The Plan shall become effective upon its adoption by the
        ------------
Board.  It shall continue in effect for a term of ten (10) years unless
terminated earlier under Section 14 of the Plan.

    8.  Term of Option.  The term of each Option shall be stated in the Option
        --------------
Agreement.

    9.  Option Exercise Price and Consideration.
        ---------------------------------------

        (a) Exercise Price. The per share exercise price for the Shares to be
            --------------
issued pursuant to exercise of an Option shall be determined by the
Administrator.

        (b) Waiting Period and Exercise Dates.  At the time an Option is
            ---------------------------------
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

        (c) Form of Consideration.  The Administrator shall determine the
            ---------------------
acceptable form of consideration for exercising an Option, including the method
of payment.  Such consideration may consist entirely of:

            (i)  cash;

            (ii)  check;

                                      -5-
<PAGE>

            (iii)  promissory note;

            (iv) other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

            (v) consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan;

            (vi) a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

            (vii)  any combination of the foregoing methods of payment; or

            (viii)  such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

    10.  Exercise of Option.
         ------------------

        (a) Procedure for Exercise; Rights as a Stockholder. Any Option granted
            -----------------------------------------------
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.  Unless the Administrator provides otherwise, vesting
of Options granted hereunder shall be tolled during any unpaid leave of absence.
An Option may not be exercised for a fraction of a Share.

            An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

                                      -6-
<PAGE>

            Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

        (b) Termination of Relationship as a Service Provider.  If an Optionee
            -------------------------------------------------
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement).  In the absence
of a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination.  If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

        (c) Disability of Optionee.  If an Optionee ceases to be a Service
            ----------------------
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement).  In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination.  If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan.  If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

        (d) Death of Optionee.  If an Optionee dies while a Service Provider,
            -----------------
the Option may be exercised within such period of time as is specified in the
Option Agreement (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquires the right to exercise the Option by bequest or inheritance,
but only to the extent that the Option is vested on the date of death.  In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination.  If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan.  The Option may be exercised by the executor or
administrator of the Optionee's estate or, if none, by the person(s) entitled to
exercise the Option under the Optionee's will or the laws of descent or
distribution.  If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

        (e) Buyout Provisions.  The Administrator may at any time offer to buy
            -----------------
out for a payment in cash or Shares an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

                                      -7-
<PAGE>

    11.  Non-Transferability.  Unless determined otherwise by the Administrator,
         -------------------
an Option may not be sold, pledged, assigned, hypothecated, transferred, or
disposed of in any manner other than by will or by the laws of descent or
distribution and may be exercised, during the lifetime of the Optionee, only by
the Optionee.  If the Administrator makes an Option transferable, such Option
shall contain such additional terms and conditions as the Administrator deems
appropriate.

    12. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset
        ------------------------------------------------------------------------
        Sale.
        ----

        (a) Changes in Capitalization.  Subject to any required action by the
            -------------------------
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

        (b) Dissolution or Liquidation.  In the event of the proposed
            --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable.  In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated.  To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

        (c) Merger or Asset Sale. In the event of a merger of the Company with
            --------------------
or into another corporation, or the sale of substantially all of the assets of
the Company (a "Merger"), each outstanding Option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation (the "Successor Corporation").

        Following such assumption or substitution in connection with a Merger,
if the Optionee's status as an Employee or employee of the Successor
Corporation, as applicable, is

                                      -8-
<PAGE>

terminated by the Successor Corporation as a result of an Involuntary
Termination (as defined below) other than for Cause (as defined below) within
twelve months following a Merger, the Optionee shall fully vest in and have the
right to exercise Optionee's Option as to all of the Optioned Stock, including
Shares as to which Optionee would not otherwise be vested or exercisable.
Thereafter, the Option shall remain exercisable in accordance with Sections
10(b) through (d) above.

         For purposes of this section, any of the following events shall
constitute an "Involuntary Termination":  (i) without the Employee's express
written consent, a significant reduction of the Employee's duties, authority or
responsibilities, relative to the Employee's duties, authority or
responsibilities as in effect immediately prior to the Merger, or the assignment
to Employee of such reduced duties, authority or responsibilities; (ii) without
the Employee's express written consent, a substantial reduction, without good
business reasons, of the facilities and perquisites (including office space and
location) available to the Employee immediately prior to the Merger; (iii) a
reduction by the Successor Corporation in the base salary of the Employee as in
effect immediately prior to the Merger; (iv) a material reduction by the
Successor Corporation in the kind or level of employee benefits, including
bonuses, to which the Employee was entitled immediately prior to the Merger with
the result that the Employee's overall benefits package is significantly
reduced; (v) the relocation of the Employee to a facility or a location more
than fifty (50) miles from the Employee's then present location, without the
Employee's express written consent; (vi) any purported termination of the
Employee by the Corporation which is not effected for Disability or for Cause,
or any purported termination for which the grounds relied upon are not valid;
(vii) or any act or set of facts or circumstances which would, under California
case law or statute constitute a constructive termination of the Employee.

        For purposes of this section, "Cause" shall mean (i) any act of personal
dishonesty taken by the Employee in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Employee, (ii) the conviction of a felony, (iii) a willful act by the Employee
which constitutes gross misconduct and which is injurious to the Successor
Corporation, and (iv) following delivery to the Employee of a written demand for
performance from the Successor Corporation which describes the basis for the
Successor Corporation's belief that the Employee has not substantially performed
his duties, continued violations by the Employee of the Employee's obligations
to the Successor which are demonstrably willful and deliberate on the Employee's
part.

        In the event that the Successor Corporation refuses to assume or
substitute for the Option, the Optionee shall fully vest in and have the right
to exercise the Option as to all of the Optioned Stock, including Shares as to
which Optionee would not otherwise be vested or exercisable.  If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Administrator shall notify the
Optionee in writing or electronically that the Option shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period.  For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option confers the right to purchase or receive,
for each Share of Optioned Stock

                                      -9-
<PAGE>

subject to the Option immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received in
the merger or sale of assets by holders of Common Stock for each Share held on
the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided, however, that if such consideration received
in the merger or sale of assets is not solely common stock of the Successor
Corporation or its Parent, the Administrator may, with the consent of the
Successor Corporation, provide for the consideration to be received upon the
exercise of the Option, for each Share of Optioned Stock subject to the Option,
to be solely common stock of the Successor Corporation or its Parent equal in
fair market value to the per share consideration received by holders of Common
Stock in the merger or sale of assets.

    13.  Date of Grant.  The date of grant of an Option shall be, for all
         -------------
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

    14.  Amendment and Termination of the Plan.
         -------------------------------------

        (a) Amendment and Termination.  The Board may at any time amend, alter,
            -------------------------
suspend or terminate the Plan.

        (b) Effect of Amendment or Termination.  No amendment, alteration,
            ----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

    15.   Conditions Upon Issuance of Shares.

     ---------

    1   Grant of Option.  The Plan Administrator of the Company hereby grants to
        ---------------
the Optionee named in the Notice of Grant attached as Part I of this Agreement
(the "Optionee") an option (the "Option") to purchase the number of Shares, as
set forth in the Notice of Grant, at the exercise price per share set forth in
the Notice of Grant (the "Exercise Price"), subject to the terms and conditions
of the Plan, which is incorporated herein by reference.  Subject to Section
14(b) of the Plan, in the event of a conflict between the terms and conditions
of the Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

    2   Exercise of Option.
        ------------------

        (a) Right to Exercise.  This Option is exercisable during its term in
            -----------------
accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

        (b) Method of Exercise.  This Option is exercisable by delivery of an
            ------------------
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan.  The Exercise Notice shall be completed
by the Optionee and delivered to [Title] of the Company.  The Exercise Notice
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares.  This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.

        No Shares shall be issued pursuant to the exercise of this Option unless
such issuance and exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

    3   Method of Payment.  Payment of the aggregate Exercise Price shall be by
        -----------------
any of the following, or a combination thereof, at the election of the Optionee:

        (a)  cash;

        (b)  check;

        (c) consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

                                      -2-
<PAGE>

        (d) surrender of other Shares which (i) in the case of Shares acquired
upon exercise of an option, have been owned by the Optionee for more than six
(6) months on the date of surrender, and (ii) have a Fair Market Value on the
date of surrender equal to the aggregate Exercise Price of the Exercised Shares;
or

        (e) with the Administrator's consent, delivery of Optionee's promissory
note (the "Note") in the form attached hereto as Exhibit C, in the amount of the
aggregate Exercise Price of the Exercised Shares together with the execution and
delivery by the Optionee of the Security Agreement attached hereto as Exhibit B.
The Note shall bear interest at the "applicable federal rate" prescribed under
the Code and its regulations at time of purchase, and shall be secured by a
pledge of the Shares purchased by the Note pursuant to the Security Agreement.

    4   Non-Transferability of Option.  This Option may not be transferred in
        -----------------------------
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee.  The
terms of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

    5   Term of Option.  This Option may be exercised only within the term set
        --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

    6   Tax Consequences.  Some of the federal tax consequences relating to this
        ----------------
Option, as of the date of this Option, are set forth below.  THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
DISPOSING OF THE SHARES.

        (a) Exercising the Option.  The Optionee may incur regular federal
            ---------------------
income tax liability upon exercise of a NSO.  The Optionee 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 Exercised Shares on the
date of exercise over their aggregate Exercise Price.  If the Optionee is an
Employee or a former Employee, the Company will be required to withhold from his
or her compensation or collect from Optionee and pay to the applicable taxing
authorities an amount in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

        (b) Disposition of Shares.  If the Optionee holds NSO Shares for at
            ---------------------
least one year, any gain realized on disposition of the Shares will be treated
as long-term capital gain for federal income tax purposes.

                                      -3-

and securities laws, of the Code, and of any applicable stock exchange (the
"Applicable Laws"). Once appointed, such Committee shall continue to serve in
its designated capacity until otherwise directed by the Board. From time to time
the Board may increase the size of the Committee and appoint additional members
thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies, however caused, and remove all members of
the Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws.

          (c) Powers of the Administrator.  Subject to the provisions of the
              ---------------------------
Plan and, in the case of a Committee, the specific duties delegated by the Board
to such Committee, and subject to the approval of any relevant authorities,
including the approval, if required, of any stock exchange upon which the Common
Stock is listed, the Administrator shall have the authority, in its discretion:

                  (1) to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(k) of the Plan;

                                                                    Page 3 of 22
<PAGE>

                  (2) to select the Consultants and Employees to whom Options
may from time to time be granted hereunder;

                  (3) to determine whether and to what extent Options are
granted hereunder;

                  (4) to determine the number of shares of Common Stock to be
covered by each such award granted hereunder;

                  (5) to approve forms of agreement for use under the Plan;

                  (6) to determine the terms and conditions of any award granted
hereunder;

                  (7) to allow Optionees to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option that number of Shares having a Fair Market Value equal to
the amount required to be withheld. The Fair Market Value of the Shares to be
withheld shall be determined on the date that the amount of tax to be withheld
is to be determined. All elections by Optionees to have Shares withheld for this
purpose shall be made in such form and under such conditions as the
Administrator may deem necessary or advisable;

                  (8) to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option has declined since the date the Option was granted; and

                  (9) to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

          (d) Effect of Administrator's Decision.  All decisions, determinations
              ----------------------------------
and interpretations of the Administrator shall be final and binding on all
Optionees and any other holders of any Options.

     5.  Eligibility.
         -----------

          (a) Nonstatutory Stock Options may be granted to Employees and
Consultants.  Incentive Stock Options may be granted only to Employees.  An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

          (b) Each Option shall be designated in the written option agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options.  For purposes of this
Section 5(b), Incentive Stock Options shall be taken into account in the order
in which they were granted.  The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (c) The Plan shall not confer upon any Optionee any right with respect
to continuation of employment or consulting relationship with the Company, nor
shall it interfere in any way with his or her right or the Company's right to
terminate his or her employment or consulting relationship at any time, with or
without cause.

          (d) Upon the Company or a successor corporation issuing any class of
common equity securities required to be registered under Section 12 of the
Exchange Act or upon the Plan being assumed by a corporation having a class of
common equity securities required to be registered under Section 12 of the
Exchange Act, the following limitations shall apply to grants of Options to
Employees:

                  (1) No Employee shall be granted, in any fiscal year of the
Company, Options to purchase more than 5,000,000 Shares.

                                                                    Page 4 of 22
<PAGE>

                  (2) In connection with his or her initial employment, an
Employee may be granted Options to purchase up to an additional 3,000,000 Shares
which shall not count against the limit set forth in subsection (i) above.

                  (3) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11.

                  (4) If an Option is cancelled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 11), the cancelled Option will be counted against the limit
set forth in subsection (i) above. For this purpose, if the exercise price of an
Option is reduced, the transaction will be treated as a cancellation of the
Option and the grant of a new Option.

     6.  Term of Plan.  The Plan shall become effective upon the earlier to
         ------------
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company, as described in Section 17 of the Plan.  It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 13 of the Plan.

     7.  Term of Option.  The term of each Option shall be the term stated in
         --------------
the Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof.  However, in the case of an Incentive
Stock Option granted to an Optionee who, at the time the Option is granted, owns
stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five (5) years from the date of grant thereof or such shorter
term as may be provided in the Option Agreement.

     8.  Option Exercise Price and Consideration.
         ---------------------------------------

          (a) The per share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the
Administrator, but shall be subject to the following:

                  (1) In the case of an Incentive Stock Option

                      (A) granted to an Employee who, at the time of the grant
of such Incentive Stock Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than one hundred
ten percent (110%) of the Fair Market Value per Share on the date of grant.

                      (B) granted to any Employee other than an Employee
described in the preceding paragraph, the per Share exercise price shall be no
less than one hundred percent (100%) of the Fair Market Value per Share on the
date of grant.

                  (2) In the case of a Nonstatutory Stock Option

                      (A) granted to a person who, at the time of the grant of
such Option, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
per Share exercise price shall be no less than one hundred ten percent (110%) of
the Fair Market Value per Share on the date of the grant.

                      (B) granted to any person, the per Share exercise price
shall be no less than eighty-five (85%) of the Fair Market Value per Share on
the date of grant.

          (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option have been owned by the Optionee for more
than six months on the date of surrender and (y) have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable,

                                                                    Page 5 of 22
<PAGE>

shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price, (6) the
cancellation of a portion of the Shares subject to the Option with a Fair Market
Value equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised, or (7) any combination of the foregoing methods of
payment. In making its determination as to the type of consideration to accept,
the Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

     9.  Exercise of Option.
         ------------------

          (a) Procedure for Exercise; Rights as a Stockholder.  Any Option
              -----------------------------------------------
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan. Except in the case of Options granted to Officers, Directors and
Consultants, Options shall become exercisable at a rate of no less than 20% per
year over five (5) years from the date the Options are granted.

          An Option may not be exercised for a fraction of a Share.

          An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under Section 8(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option.  The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the Option. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

          Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b) Termination of Employment or Consulting Relationship.  In the
              ----------------------------------------------------
event of termination of an Optionee's Continuous Status as an Employee or
Consultant with the Company (but not in the event of an Optionee's change of
status from Employee to Consultant (in which case an Employee's Incentive Stock
Option shall automatically convert to a Nonstatutory Stock Option on the date
three (3) months and one (1) day from the date of such change of status) or from
Consultant to Employee), such Optionee may, but only within such period of time
as is determined by the Administrator, of at least thirty (30) days, with such
determination in the case of an Incentive Stock Option not exceeding three (3)
months after the date of such termination (but in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), exercise his or her Option to the extent that Optionee was entitled
to exercise it at the date of such termination. To the extent that Optionee was
not entitled to exercise the Option at the date of such termination, or if
Optionee does not exercise such Option to the extent so entitled within the time
specified herein, the Option shall terminate.

          (c) Disability of Optionee.  In the event of termination of an
              ----------------------
Optionee's consulting relationship or Continuous Status as an Employee as a
result of his or her disability, Optionee may, but only within twelve (12)
months from the date of such termination (and in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), exercise the Option to the extent otherwise entitled to exercise it
at the date of such termination; provided, however, that if such disability is
not a "disability" as such term is defined in Section 22(e)(3) of the Code, in
the case of an Incentive Stock Option such Incentive Stock Option shall
automatically convert to a Nonstatutory Stock Option on the day three (3) months
and one (1) day following such termination.  To the extent that Optionee is not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option to the extent so entitled within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

                                                                    Page 6 of 22
<PAGE>

          (d) Death of Optionee.  In the event of the death of an Optionee, the
              -----------------
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent that the Optionee was entitled to exercise the Option at the
date of death.  If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan.  If, after death,
the Optionee's estate or a person who acquired the right to exercise the Option
by bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

               (e) Rule 16b-3.  Options granted to persons subject to Section
                   ----------
16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

     10.  Non-Transferability of Options.  Options may not be sold, pledged,
          ------------------------------
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

     11.  Adjustments Upon Changes in Capitalization or Merger.
          ----------------------------------------------------

               (a) Changes in Capitalization.  Subject to any required action
                   -------------------------
by the stockholders of the Company, the number of shares of Common Stock covered
by each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the
Administrator, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an Option.

               (b) Dissolution or Liquidation.  In the event of the proposed
                   --------------------------
dissolution or liquidation of the Company, the Administrator shall notify the
Optionee at least fifteen (15) days prior to such proposed action.  To the
extent it has not been previously exercised, the Option will terminate
immediately prior to the consummation of such proposed action.

               (c) Merger or Asset Sale.  In the event of a merger of the
                   --------------------
Company with or into another corporation, or the sale of substantially all of
the assets of the Company, each outstanding Option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option, the Optionee shall
fully vest in and have the right to exercise the Option as to all of the
Optioned Stock, including Shares as to which it would not otherwise be vested or
exercisable. If an Option becomes fully vested and exercisable in lieu of
assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option shall be fully vested and exercisable for a period of fifteen (15) days
from the date of such notice, and the Option shall terminate upon the expiration
of such period. For the purposes of this paragraph, the Option shall be
considered assumed if, following the merger or sale of assets, the option
confers the right to purchase or receive, for each Share of Optioned Stock
subject to the Option immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received in
the merger or sale of assets by holders of Common Stock for each Share held on
the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided, however, that if such consideration received
in the merger or sale of assets is not solely common stock of the successor
corporation or its Parent, the Administrator may, with the consent of the

                                                                    Page 7 of 22

<PAGE>

successor corporation, provide for the consideration to be received upon the
exercise of the Option, for each Share of Optioned Stock subject to the Option,
to be solely common stock of the successor corporation or its Parent equal in
fair market value to the per share consideration received by holders of Common
Stock in the merger or sale of assets.

     12.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board.  Notice
of the determination shall be given to each Employee or Consultant to whom an
Option is so granted within a reasonable time after the date of such grant.

     13.  Amendment and Termination of the Plan.  The Board may at any time
          -------------------------------------
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her written consent.
In addition, to the extent necessary and desirable to comply with Rule 16b-3
under the Exchange Act or with Sections 162(m) or 422 of the Code (or any other
applicable law or regulation, including the requirements of the NASD or an
established stock exchange), the Company shall obtain stockholder approval of
any Plan amendment in such a manner and to such a degree as required.

     14.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

          As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

     15.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

     16.  Agreements.  Options shall be evidenced by written agreements in such
          ----------
form as the Administrator shall approve from time to time.

     17.  Stockholder Approval.  Continuance of the Plan shall be subject to
          --------------------
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such stockholder approval shall be obtained
in the degree and manner required under applicable state and federal law and the
rules of any stock exchange upon which the Common Stock is listed.

     18.  Information to Optionees and Purchasers.  The Company shall provide to
          ---------------------------------------
each Optionee, not less frequently than annually, copies of annual financial
statements.  The Company shall also provide such statements to each individual
who acquires Shares pursuant to the Plan while such individual owns such Shares.
The Company shall not be required to provide such statements to key employees
whose duties in connection with the Company assure their access to equivalent
information.

                                                                    Page 8 of 22

II.  AGREEMENT
     ---------

         (a)  Grant of Option. Seagate Software Information Management Group
              ---------------
     Holdings, Inc. a Delaware corporation (the "Company"), hereby grants to the
     Optionee named in the Notice of Grant (the "Optionee"), an option (the
     "Option") to purchase the total number of shares of Common Stock (the
     "Shares") set forth in the Notice of Grant, at the exercise price per share
     set forth in the Notice of Grant (the "Exercise Price") subject to the
     terms, definitions and provisions of the 1999 Stock Option Plan (the
     "Plan") adopted by the Company, which is incorporated herein by reference.
     Unless otherwise defined herein, the terms defined in the Plan shall have
     the same defined meanings in this Option Agreement.

                 If designated in the Notice of Grant as an Incentive Stock
               Option ("ISO"), this Option is intended to qualify as an
               Incentive Stock Option as defined in Section 422 of the Code.
               Nevertheless, to the extent that it exceeds the $100,000 rule of
               Code Section 422(d), this Option shall be treated as a
               Nonstatutory Stock Option ("NSO").

(b)  Exercise of Option.
     ------------------

     (1)  Right to Exercise.  This Option shall be exercisable during its term
          -----------------
          in accordance with the Vesting Schedule set out in the Notice of Grant
          and with the applicable provisions of the Plan and this Option
          Agreement. In the event of Optionee's death, disability or other
          termination of the employment or consulting relationship, this Option
          shall be exercisable in accordance with the applicable provisions of
          the Plan and this Option Agreement.

     (2)  Method of Exercise.  This Option shall be exercisable by written
          ------------------
          notice (in the form attached as Exhibit A) which shall state the
                                          ---------
          election to exercise the Option, the number of Shares in respect of
          which the Option is being exercised, and such other representations
          and agreements as to the holder's investment intent with respect to
          such shares of Common Stock as may be required by the Company pursuant
          to the provisions of the Plan. Such written notice shall be signed by
          the Optionee and shall be delivered in person or by certified mail to
          the Secretary of the Company. The written notice shall be accompanied
          by payment of the Exercise Price. This Option shall be deemed to be
          exercised upon receipt by the Company of such written notice
          accompanied by the Exercise Price.

No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange upon which the Shares may then be listed.
Assuming such compliance, for income tax purposes the Shares shall be considered
transferred to the Optionee on the date on which the Option is exercised with
respect to such Shares.

                                                                   Page 10 of 22

     (c)  Optionee's Representations.  In the event the Shares purchasable
          --------------------------
          pursuant to the exercise of this Option have not been registered under
          the Securities Act of 1933, as amended, at the time this Option is
          exercised, Optionee shall, if required by the Company, concurrently
          with the exercise of all or any portion of this Option, deliver to the
          Company his or her Investment Representation Statement in the form
          attached hereto as Exhibit B, and shall read the applicable rules of
                             ---------
          the Commissioner of Corporations attached to such Investment
          Representation Statement.

     (d)  Lock-Up Period. Optionee hereby agrees that if so requested by the
          --------------
          Company or any representative of the underwriters (the "Managing
          Underwriter") in connection with any registration of the offering of
          any securities of the Company under the Securities Act, Optionee shall
          not sell or otherwise transfer any Shares or other securities of the
          Company during the 180-day period (or such longer period as may be
          requested in writing by the Managing Underwriter and agreed to in
          writing by the Company) (the "Market Standoff Period") following the
          effective date of a registration statement of the Company filed under
          the Securities Act; provided, however, that such restriction shall
          apply only to the first registration statement of the Company to
          become effective under the Securities Act that includes securities to
          be sold on behalf of the Company to the public in an underwritten
          public offering under the Securities Act. The Company may impose stop-
          transfer instructions with respect to securities subject to the
          foregoing restrictions until the end of such Market Standoff Period.

     (e)  Method of Payment. Payment of the Exercise Price shall be by any of
          -----------------
          the following, or a combination thereof, at the election of the
          Optionee:

          (1)   cash;

          (2)   check;

          (3)   surrender of other shares of Common Stock of the Company which
                (A) in the case of Shares acquired pursuant to the exercise of a
                Company option, have been owned by the Optionee for more than
                six (6) months on the date of surrender, and (B) have a Fair
                Market Value on the date of surrender equal to the Exercise
                Price of the Shares as to which the Option is being exercised;
                or

         (4)   delivery of a properly executed exercise notice together with
               such other documentation as the Administrator and the broker, if
               applicable, shall require to effect an exercise of the Option and
               delivery to the Company of the sale or loan proceeds required to
               pay the Exercise Price.

    (f)  Restrictions on Exercise. This Option may not be exercised until such
         ------------------------
         time as the Plan has been approved by the stockholders of the Company,
         or if the issuance of such Shares upon such exercise or the method of
         payment of consideration for such shares would constitute a violation
         of any applicable federal or state securities or other law or
         regulation, including any rule under Part 207 of Title 12 of the Code
         of Federal Regulations ("Regulation G") as promulgated by the Federal
         Reserve Board.

    (g)  Termination of Relationship. In the event an Optionee's Continuous
         ---------------------------
         Status as an Employee or Consultant terminates, Optionee may, to the
         extent otherwise so entitled at the date of such termination (the
         "Termination Date"), exercise this Option during the Termination Period
         set out in the Notice of Grant. To the extent that Optionee was not
         entitled to exercise this Option at the date of such termination, or if
         Optionee does not exercise this Option within the time specified
         herein, the Option shall terminate.

    (h)  Disability of Optionee. Notwithstanding the provisions of Section 7
         ----------------------
         above, in the event of termination of an Optionee's consulting
         relationship or Continuous Status as an Employee as a result of his or
         her disability, Optionee may, but only within twelve (12) months from
         the date of such termination (and in no event later than the expiration
         date of the term of such Option as set forth in the Option Agreement),
         exercise the Option to the extent otherwise entitled to exercise it at
         the date of such termination; provided, however, that if such
         disability is not a "disability" as such term is defined in Section
         22(e)(3) of the Code, in the case of an Incentive Stock Option such
         Incentive Stock Option shall cease to be treated as an Incentive Stock
         Option and shall be treated for tax purposes as a Nonstatutory Stock
         Option on the day three months and one day following such termination.
         To the extent that Optionee was not entitled to

                                                                   Page 11 of 22
<PAGE>

     exercise the Option at the date of termination, or if Optionee does not
     exercise such Option to the extent so entitled within the time specified
     herein, the Option shall terminate, and the Shares covered by such Option
     shall revert to the Plan.

(i)  Death of Optionee.  In the event of termination of Optionee's Continuous
     -----------------
     Status as an Employee or Consultant as a result of the death of Optionee,
     the Option may be exercised at any time within twelve (12) months following
     the date of death (but in no event later than the date of expiration of the
     term of this Option as set forth in Section 11 below), by Optionee's estate
     or by a person who acquired the right to exercise the Option by bequest or
     inheritance, but only to the extent the Optionee could exercise the Option
     at the date of death.

(j)  Non-Transferability of Option.  This Option may not be transferred in any
     -----------------------------
     manner otherwise than by will or by the laws of descent or distribution and
     may be exercised during the lifetime of Optionee only by Optionee.  The
     terms of this Option shall be binding upon the executors, administrators,
     heirs, successors and assigns of the Optionee.

(k)  Term of Option.  This Option may be exercised only within the term set out
     --------------
     in the Notice of Grant, and may be exercised during such term only in
     accordance with the Plan and the terms of this Option.  The limitations set
     out in Section 7 of the Plan regarding Options designated as Incentive
     Stock Options and Options granted to more than ten percent (10%)
     stockholders shall apply to this Option.

(l)  Tax Consequences.  Set forth below is a brief summary as of the date of
     ----------------
     this Option of some of the federal and state tax consequences of exercise
     of this Option and disposition of the Shares.  THIS SUMMARY IS NECESSARILY
     INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
     OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
     DISPOSING OF THE SHARES.

          (1)  Exercise of ISO. If this Option qualifies as an ISO, there will
               ---------------
               be no regular federal income tax liability or state 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 an adjustment
               to the alternative minimum tax for federal tax purposes and may
               subject the Optionee to the alternative minimum tax in the year
               of exercise.

          (2)  Exercise of ISO Following Disability. If the Optionee's
               ------------------------------------
               Continuous Status as an Employee or Consultant terminates as a
               result of disability that is not total and permanent disability
               as defined in Section 22(e)(3) of the Code, to the extent
               permitted on the date of termination, the Optionee must exercise
               an ISO within three months of such termination for the ISO to be
               qualified as an ISO.

          (3)  Exercise of Nonstatutory Stock Option. There may be a regular
               -------------------------------------
               federal income tax liability and state income tax liability upon
               the exercise of a Nonstatutory Stock Option. The Optionee 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 Optionee is an Employee or a former Employee,
               the Company will be required to withhold from Optionee's
               compensation or collect from Optionee and pay to the applicable
               taxing authorities an amount in cash equal to a percentage of
               this compensation income at the time of exercise, and may refuse
               to honor the exercise and refuse to deliver Shares if such
               withholding amounts are not delivered at the time of exercise.

          (4)  Disposition of Shares. In the case of an NSO, if Shares are held
               ---------------------
               for at least one year, any gain realized on disposition of the
               Shares will be treated as long-term capital gain for federal and
               state income tax purposes. In the case of an ISO, if Shares
               transferred pursuant to the Option are held for at least one year
               after exercise and are disposed of at least two years after the
               Date of Grant, any gain realized on disposition of the Shares
               will also be treated as long-term capital gain for federal and
               state income tax purposes. If Shares purchased under an ISO are
               disposed of within such one-year period or within two years after
               the Date of Grant, any gain realized on such

                                                                   Page 12 of 22
<PAGE>

               disposition will be treated as compensation income (taxable at
               ordinary income rates) to the extent of the difference between
               the Exercise Price and the lesser of (1) the Fair Market Value of
               the Shares on the date of exercise, or (2) the sale price of the
               Shares.

          (5)  Notice of Disqualifying Disposition of ISO Shares. If the Option
               -------------------------------------------------
               granted to Optionee herein is an ISO, and if Optionee sells or
               otherwise disposes of any of the Shares acquired pursuant to the
               ISO on or before the later of (1) the date two years after the
               Date of Grant, or (2) the date one year after the date of
               exercise, the Optionee shall immediately notify the Company in
               writing of such disposition. Optionee agrees that Optionee may be
               subject to income tax withholding by the Company on the
               compensation income recognized by the Optionee.

 (m) Entire Agreement; Governing Law.  The Plan is incorporated herein by
     -------------------------------
     reference. The Plan and this Option Agreement constitute the entire
     agreement of the parties with respect to the subject matter hereof and
     supersede in their entirety all prior undertakings and agreements of the
     Company and Optionee with respect to the subject matter hereof, and may not
     be modified adversely to the Optionee's interest except by means of a
     writing signed by the Company and Optionee. This agreement is governed by
     California law except for that body of law pertaining to conflict of laws.

payment for the Shares so purchased in accordance with the provisions of this
Agreement, and Optionee shall forthwith cause the certificate(s) evidencing the
Shares so purchased to be surrendered to the Company for transfer or

"Right of First Refusal").

          (a)  Notice of Proposed Transfer.  The Holder of the Shares shall
               ---------------------------
     deliver to the Company a written notice (the "Notice") stating: (i) the
     Holder's bona fide intention to sell or otherwise transfer such Shares;

     less than all, of the Shares proposed to be transferred to any one or more
     of the Proposed Transferees, at the purchase price determined in accordance
     with subsection (c) below.

          (c)  Purchase Price. The purchase price ("Purchase Price") for the

     be the Offered Price. If the Offered Price includes consideration other
     than cash, the cash equivalent value of the non-cash consideration shall be
     determined by the Board of Directors of the Company in good faith.

          (d)  Payment.  Payment of the Purchase Price shall be made, at the
               -------
     option of the Company or its assignee(s), in cash (by check), by
     cancellation of all or a portion of any outstanding indebtedness of the
     Holder to the Company (or, in the case of repurchase by an assignee, to the

     the Notice or in the manner and at the times set forth in the Notice.

          (e)  Holder's Right to Transfer.  If all of the Shares proposed in the
               --------------------------
     Notice to be transferred to a given Proposed Transferee are not purchased

     sale or other transfer is consummated within 120 days after the date of the
     Notice and provided further that any such sale or other transfer is
     effected in accordance with any applicable securities laws and the Proposed
     Transferee agrees in writing that the provisions of this Section shall
     continue to apply to the Shares in the hands of such Proposed Transferee.

     Transferee within such period, a new Notice shall be given to the Company,

     contained in this Section notwithstanding, the transfer of any or all of
     the Shares during the Optionee's lifetime or on the Optionee's death by
     will or intestacy to the Optionee's immediate family or a trust for the
     benefit of the Optionee's immediate family shall be exempt from the
     provisions of this Section. "Immediate Family" as used herein shall mean
