it to be desirable to qualify Options granted hereunder as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the Plan shall
be administered by a Committee of two or more "outside directors" within the
meaning of Section 162(m) of the Code.

        (iii)  Rule 16b-3.  To the extent desirable to qualify transactions
               ----------
hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder
shall be structured to satisfy the requirements for exemption under Rule 16b-3.

         (iv)  Other Administration.  Other than as provided above, the Plan
               --------------------
shall be administered by (A) the Board or (B) a Committee, which committee shall
be constituted to satisfy Applicable Laws.

                                      -4-


  (b)  Powers of the Administrator. Subject to the provisions of the Plan, and
       ---------------------------
in the case of a Committee, subject to the specific duties delegated by the
Board to such Committee, the Administrator shall have the authority, in its
discretion:

        (i)  to determine Fair Market Value;

        (ii) to select the Service Providers to whom Options and Stock
Purchase Rights may be granted hereunder;

        (iii) to determine the number of shares of Common Stock to be covered
by each Option and Stock Purchase Right granted hereunder;

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

        (v)  to determine the terms and conditions, not inconsistent with the
terms of the Plan, of any Option or Stock Purchase Right granted hereunder. Such
terms and conditions include, but are not limited to, the exercise price, the
time or times when Options or Stock Purchase Rights may be exercised (which may
be based on performance criteria), any vesting acceleration or waiver of
forfeiture restrictions, and any restriction or limitation regarding any Option
or Stock Purchase Right or the shares of Common Stock relating 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 or Stock Purchase Right
to the then current Fair Market Value if the Fair Market Value of the Common
Stock covered by such Option or Stock Purchase Right shall have declined since
the date the Option or Stock Purchase Right 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;

        (ix) to prescribe, amend and rescind rules and regulations relating to
the Plan, including rules and regulations relating to sub-plans established for
the purpose of qualifying for preferred tax treatment under foreign tax laws;

        (x)  to modify or amend each Option or Stock Purchase Right (subject to
Section 16(c) of the Plan), including the discretionary authority to extend the
post-termination exercisability period of Options longer than is otherwise
provided for in the Plan;

        (xi) 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 or Stock Purchase Right 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 shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable;

                                      -5-


        (xii)  to authorize any person to execute on behalf of the Company any
instrument required to effect the grant of an Option or Stock Purchase Right
previously granted by 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 or Stock Purchase Rights.

 5.  Eligibility.  Nonstatutory Stock Options and Stock Purchase Rights may be
     -----------
granted to Service Providers.  Incentive Stock Options may be granted only to
Employees.

 6.  Limitations.
     -----------

  (a)  Each Option shall be designated in the 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 6(a), 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.

  (b)  Neither the Plan nor any Option or Stock Purchase Right 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.

  (c)  The following limitations shall apply to grants of Options:

        (i)  No Service Provider shall be granted, in any fiscal year of the
Company, Options to purchase more than 500,000 Shares.

        (ii) In connection with his or her initial service, a Service Provider
may be granted Options to purchase up to an additional 500,000 Shares, which
shall not count against the limit, set forth in subsection (i) above.

       (iii) The foregoing limitations shall be adjusted proportionately in
connection with any change in the Company's capitalization as described in
Section 14.

        (iv) 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 14), the cancelled Option will be counted against the limits set forth
in subsections (i) and (ii) 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-


  7.  Term of Plan.  Subject to Section 20 of the 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 16 of the Plan.

  8.  Term of Option.  The term of each Option shall be stated in the Option
      --------------
Agreement.  In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.  Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided 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, subject to the following:

        (i)  In the case of an Incentive Stock Option

          (A)  granted to an Employee who, at the time the Incentive Stock
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 per Share exercise price shall be no less than 110% of the Fair Market Value
per Share on the date of grant.

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

        (ii) In the case of a Nonstatutory Stock Option, the per Share exercise
price shall be determined by the Administrator. In the case of a Nonstatutory
Stock Option intended to qualify as "performance-based compensation" within the
meaning of Section 162(m) of the Code, the per Share exercise price shall be no
less than 100% of the Fair Market Value per Share on the date of grant.

       (iii) Notwithstanding the foregoing, Options may be granted with a per
Share exercise price of less than 100% of the Fair Market Value per Share on the
date of grant pursuant to a merger or other corporate transaction.

   (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 that 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.
In the case of an Incentive Stock Option, the Administrator shall determine the
acceptable form of consideration at the time of grant. Such consideration may
consist entirely of:

                                      -7-


        (i)  cash;

        (ii) check;

       (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 (6) 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 Shareholder.  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 shareholder 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 14 of the Plan.

                                      -8-


       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. Subject to Section 14,
       -------------------------------------------------
     if an Optionee ceases to be a Service Provider (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 ninety-first (91st) day following such
     change of status) or from Consultant to Employee), such Optionee may, but
     only within such period of time as is specified in the Option Agreement,
     and 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. 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, 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 his or her Option the extent the Option is
     vested on the date of termination. If such disability is not a Disability,
     in the case of an Incentive Stock Option such Incentive Stock Option shall
     automatically 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
     (3) months and one day following such 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 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 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. 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.

                                      -9-


  (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.

 11.  Stock Purchase Rights.
      ---------------------

  (a)  Rights to Purchase.  Stock Purchase Rights may be issued either alone, in
       ------------------
     addition to, or in tandem with other awards granted under the Plan and/or
     cash awards made outside of the Plan.  After the Administrator determines
     that it will offer Stock Purchase Rights under the Plan, it shall advise
     the offeree in writing or electronically, by means of a Notice of Grant, of
     the terms, conditions and restrictions related to the offer, including the
     number of Shares that the offeree shall be entitled to purchase, the price
     to be paid, and the time within which the offeree must accept such offer,
     which shall not exceed ninety (90) days from the date upon which the
     Administrator makes the determination to grant the Stock Purchase Right.
     The offer shall be accepted by execution of a Restricted Stock Purchase
     Agreement in the form determined by the Administrator.

  (b)  Repurchase Option.  Unless the Administrator determines otherwise, the
       -----------------
     Restricted Stock Purchase Agreement shall grant the Company a repurchase
     option exercisable upon the voluntary or involuntary termination of the
     purchaser's service with the Company for any reason (including death or
     Disability).  The purchase price for Shares repurchased pursuant to the
     Restricted Stock Purchase Agreement shall be the original price paid by the
     purchaser and may be paid by cancellation of any indebtedness of the
     purchaser to the Company.  The repurchase option shall lapse at a rate
     determined by the Administrator.

  (c)  Other Provisions.  The Restricted Stock Purchase Agreement shall contain
       ----------------
     such other terms, provisions and conditions not inconsistent with the Plan
     as may be determined by the Administrator in its sole discretion.

  (d)  Rights as a Shareholder.  Once the Stock Purchase Right is exercised, the
       -----------------------
     purchaser shall have the rights equivalent to those of a shareholder, and
     shall be a shareholder when his or her purchase is entered upon the records
     of the duly authorized transfer agent of the Company.  No adjustment will
     be made for a dividend or other right for which the record date is prior to
     the date the Stock Purchase Right is exercised, except as provided in
     Section 14 of the Plan.

 12.  Non-Transferability of Options and Stock Purchase Rights.  Unless
      --------------------------------------------------------
determined otherwise by the Administrator, an Option or Stock Purchase Right 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 or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

 13.  Formula Option Grants to Outside Directors. Outside Directors shall be
      ------------------------------------------
automatically granted Options each year in accordance with the following
provisions:

                                      -10-


  (a)  All Options granted pursuant to this Section 13 shall be Nonstatutory
     Stock Options and, except as otherwise provided herein, shall be subject to
     the other terms and conditions of the Plan.

  (b)  Each person who first becomes an Outside Director on or after the IPO
     Effective Date, whether through election by the stockholders of the Company
     or appointment by the Board to fill a vacancy, and who did not hold
     unvested Options as of the IPO Effective Date, shall be automatically
     granted an Option to purchase 12,500 Shares (the "First Option") on the
     date he or she first becomes an Outside Director; provided, however, that
     an Inside Director who ceases to be an Inside Director but who remains a
     Director shall not receive a First Option.

  (c)  Each Outside Director shall be automatically granted an Option to
     purchase 5,000 Shares (a "Subsequent Option") following each annual meeting
     of the stockholders of the Company, except in the case of the first such
     annual meeting after the IPO Effective Date if such annual meeting is held
     within six (6) months of the IPO Effective Date, and if, as of such date,
     he or she shall continue to serve on the Board and shall have served on the
     Board for at least the preceding six (6) months.

  (d)  Notwithstanding the provisions of subsections (b) and (c) hereof, any
     exercise of an Option granted before the Company has obtained stockholder
     approval of the Plan in accordance with Section 20 hereof shall be
     conditioned upon obtaining such stockholder approval of the Plan in
     accordance with Section 20 hereof.

  (e)  The terms of each Option granted pursuant to this Section shall be as
     follows:

        (i)  the term of the Option shall be ten (10) years.

        (ii) the exercise price per Share shall be 100% of the Fair Market Value
     per Share on the date of grant of the Option.

       (iii) the Option shall vest and become exercisable in successive, equal
annual installments on each of the first three anniversaries of the date of
grant.

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

  (a)  Changes in Capitalization.  Subject to any required action by the
       -------------------------
     shareholders of the Company, the number of shares of Common Stock covered
     by each outstanding Option and Stock Purchase Right, the number of shares
     of Common Stock covered by First Options and Subsequent Options to be
     granted under the Plan, the number of shares of Common Stock which have
     been authorized for issuance under the Plan but as to which no Options or
     Stock Purchase Rights have yet been granted or which have been returned to
     the Plan upon cancellation or expiration of an Option or Stock Purchase
     Right, the number of shares of Common Stock which may be added to the Plan
     each year (pursuant to Section 3(i)), as well as the price per share of
     Common Stock covered by each such outstanding Option or Stock Purchase
     Right, 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

                                      -11-


     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 or Stock Purchase Right.

  (b)  Dissolution or Liquidation.  In the event of the proposed dissolution or
       --------------------------
     liquidation of the Company, the Administrator shall notify Optionee at
     least fifteen (15) days prior to such proposed action.  To the extent it
     has not been previously exercised, the Option or Stock Purchase Right shall
     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 and Stock Purchase Right shall be
     assumed or an equivalent option or right 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 or Stock Purchase Right, each outstanding Option and Stock
     Purchase Right shall terminate as of the closing of the merger or sale of
     assets. For the purposes of this paragraph, the Option or Stock Purchase
     Right shall be considered assumed if, following the merger or sale of
     assets, the option or right confers the right to purchase or receive, for
     each Share of Optioned Stock subject to the Option or Stock Purchase Right
     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 or Stock
     Purchase Right, for each Share of Optioned Stock subject to the Option or
     Stock Purchase Right, 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.

 15.  Date of Grant.  The date of grant of an Option or Stock Purchase Right
      -------------
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, 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.

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

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

                                      -12-


  (b)  Shareholder Approval.  The Company shall obtain shareholder approval of
       --------------------
     any Plan amendment to the extent necessary and desirable to comply with
     Applicable Laws.

  (c)  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.

 17.  Conditions Upon Issuance of Shares.
      ----------------------------------

  (a)  Legal Compliance.  Shares shall not be issued pursuant to the exercise of
       ----------------
     an Option or Stock Purchase Right unless the exercise of such Option or
     Stock Purchase Right and the issuance and delivery of such Shares shall
     comply with Applicable Laws and shall be further subject to the approval of
     counsel for the Company with respect to such compliance.

  (b)  Investment Representations. As a condition to the exercise of an Option
       --------------------------
     or Stock Purchase Right, the Company may require the person exercising such
     Option or Stock Purchase Right 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.

 18.  Inability to Obtain Authority.  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.

 19.  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.

 20.  Shareholder Approval.  The Plan shall be subject to approval by the
      --------------------
shareholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such shareholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

                                      -13-

     This Option may be exercised for thirty (30) days after Optionee ceases to

Term/Expiration Date as provided above.

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

    A.  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 16(c) 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.

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

B.  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 the Stock Plan Administrator
     of the Company. The Exercise Notice shall be accompanied by payment of the
     aggregate Exercise Price as to all Exercised Shares. This Option

                                      -2-


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-


 C.  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:

        1.  cash; or

        2.  check; or

        3.  consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

        4.  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.

 D.  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.

 E.  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.

 F.  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.

        1.  Exercising the Option.
            ---------------------

            (a)  Nonstatutory Stock 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

                                      -4-


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)  Incentive Stock Option.  If this Option qualifies as an ISO, the
             ----------------------
Optionee will have no regular federal income tax liability upon its exercise,
although the excess, if any, of the Fair Market Value of the Exercised Shares on
the date of exercise over their aggregate Exercise Price will be treated as an
adjustment to alternative minimum taxable income for federal tax purposes and
may subject the Optionee to alternative minimum tax in the year of exercise. In
the event that the Optionee ceases to be an Employee but remains a Service
Provider, any Incentive Stock Option of the Optionee that remains unexercised
shall cease to qualify as an Incentive Stock Option and will be treated for tax
purposes as a Nonstatutory Stock Option on the date three (3) months and one (1)
day following such change of status.

  2.  Disposition of Shares.
      ---------------------

        (a)  NSO.  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.

        (b)  ISO.  If the Optionee holds ISO Shares for at least one year after
             ---
exercise and two years after the grant date, any gain realized on disposition of
the Shares will be treated as long-term capital gain for federal income tax
purposes. If the Optionee disposes of ISO Shares within one year after exercise
or two years after the grant date, 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 lesser of (A) the difference between the Fair
Market Value of the Shares acquired on the date of exercise and the aggregate
Exercise Price, or (B) the difference between the sale price of such Shares and
the aggregate Exercise Price. Any additional gain will be taxed as capital gain,
short-term or long-term depending on the period that the ISO Shares were held.

        (c)  Notice of Disqualifying Disposition of ISO Shares.  If the Optionee
             -------------------------------------------------
sells or otherwise disposes of any of the Shares acquired pursuant to an ISO on
or before the later of (i) two years after the grant date, or (ii) one year
after the exercise date, the Optionee shall immediately notify the Company in
writing of such disposition. The Optionee agrees that he or she may be subject
to income tax withholding by the Company on the compensation income recognized
from such early disposition of ISO Shares by payment in cash or out of the
current earnings paid to the Optionee.

  G.  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 the internal substantive laws, but not the choice of law rules, of
California.

                                      -5-


  H.  NO GUARANTEE OF CONTINUED SERVICE.
      ----------------------------------

     OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE
VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT
THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED
AN OPTION OR PURCHASING SHARES HEREUNDER).  OPTIONEE FURTHER ACKNOWLEDGES AND
AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE
VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED
PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD,
FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE
COMPANY'S RIGHT TO TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT
ANY TIME, WITH OR WITHOUT CAUSE.

     By your signature and the signature of the Company's representative below,
you and the Company agree that this Option is granted under and governed by the
terms and conditions of the Plan and this Option Agreement.  Optionee has
reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
Agreement and fully understands all provisions of the Plan and Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions relating to the Plan
and Option Agreement.  Optionee further agrees to notify the Company upon any
change in the residence address indicated below.
