                 ------------------------------------
Agreement is hereby stricken and replaced in its entirety with the following:

     "If a registration pursuant to Section 3(a) involves an underwritten
offering and the managing underwriter (or underwriters) advises the Company in
writing that, in its opinion, the total number of shares of Common Stock to be
included in such registration, including the Registrable Securities requested to
be included pursuant to this Section 3, exceeds the maximum number of shares of
Common Stock specified by the managing underwriter that may be distributed
without adversely affecting the price, timing or distribution of such shares of
Common Stock, then the Company shall include in such registration only such
maximum number of Registrable Securities which, in the opinion of such
underwriter or underwriters, can be sold in the following order of priority:
(i) first, all of the shares of Common Stock that the Company proposes to sell
for its own account, if any; (ii) second, all of the shares of Common Stock
being registered by holder(s) of Registrable Securities entitled to make a
Demand Registration (as hereinafter defined) held by the party requesting such

                                                                       --------
that such amount shall be allocated among such parties on a pro rata basis based
upon their respective percentage of ownership of the total number of shares of
Common Stock then outstanding; and (iii) third, the Registrable Securities of
the holder(s) of Registrable Securities requested to be included in such
Incidental Registration.  To the extent that shares of Common Stock to be
included in the Incidental Registration must be allocated among the holder(s) of
Registrable Securities pursuant to clause (iii) above, such shares shall be
allocated pro rata among the holder(s) of Registrable Securities based on the
number of shares of Common Stock that such holder(s) of Registrable Securities
shall have requested to be included therein; provided, however, that (other than
with respect to holders of Registrable Securities that are entitled to make a
Demand Registration and Berkshire Hathaway Inc. and its Affiliates) if an
Incidental Registration is an underwritten offering, the managing underwriter or
underwriters may select shares for inclusion in such Incidental Registration on
a basis other than a pro rata basis if, in the reasonable opinion of such
underwriter or underwriters, selection on such other basis would be material to
the success of the offering."

Registrable Securities requested to be included in such Demand Registration held
by the party requesting such Demand Registration and by Berkshire Hathaway Inc.
and its Affiliates, provided that such amount shall be allocated among such
                    --------

     (w) "Plan" means this 2000 Stock Plan.

     (x) "Restricted Stock" means shares of Common Stock acquired pursuant to a
grant of a Stock Purchase Right under Section 11 below.

     (y) "Service Provider" means an Employee, Director or Consultant.

     (z) "Share" means a share of the Common Stock, as adjusted in accordance
with Section 12 below.

     (aa) "Stock Purchase Right" means a right to purchase Common Stock
pursuant to Section 11 below.

     (bb) "Subsidiary" means a "subsidiary corporation," whether now or
hereafter existing, as defined in Section 424(f) of the Code.

     3. Stock Subject to the Plan. Subject to the provisions of Section 12 of
the Plan, the maximum aggregate number of Shares that may be subject to option
and sold under the Plan is 7,630,435 Shares. The Shares may be authorized but
unissued, or reacquired Common Stock.

     If an Option or Stock Purchase Right expires or becomes unexercisable
without having been exercised in full, or is surrendered pursuant to an Option
Exchange Program, the unpurchased Shares which were subject thereto shall
become available for future grant or sale under the Plan (unless the Plan has
terminated). However, Shares that have actually been issued under the Plan,
upon exercise of either an Option or Stock Purchase Right, shall not be
returned to the Plan and shall not become available for future distribution
under the Plan, except that if Shares of Restricted Stock are repurchased by
the Company at their original purchase price, such Shares shall become
available for future grant under the Plan.

     4. Administration of the Plan.

     (a) Administrator. The Plan shall be administered by the Board or a
Committee appointed by the Board, which Committee shall be constituted to
comply with Applicable Laws.

     (b) 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, the
Administrator shall have the authority in its discretion:

          (i) to determine the Fair Market Value;

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

                                      -3-

          (iii) to determine the number of Shares to be covered by each such
     award granted hereunder;

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

          (v) to determine the terms and conditions, 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 Common Stock relating thereto, based in each case on such
     factors as the Administrator, in its sole discretion, shall determine;

          (vi) to determine whether and under what circumstances an Option may
     be settled in cash under subsection 9(e) instead of Common Stock;

          (vii) 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;

          (viii) to initiate an Option Exchange Program;

          (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 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 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; and

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

     (c) Effect of Administrator's Decision. All decisions, determinations and
interpretations of the Administrator shall be final and binding on all
Optionees.

5. Eligibility.

     (a) Nonstatutory Stock Options and Stock Purchase Rights may be granted to
Service Providers. Incentive Stock Options may be granted only to Employees.

     (b) 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

                                      -4-
<PAGE>

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) Neither the Plan nor any Option or Stock Purchase Right shall confer
upon any Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall it interfere in
any way with his or her right or the Company's right to terminate such
relationship at any time, with or without cause.

     6. 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 sooner
terminated under Section 14 of the Plan.

     7. Term of Option. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10)
years from the date of grant thereof. 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 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 upon exercise
of an Option shall be such price as is determined by the Administrator, but
shall be subject to the following:

          (i) In the case of an Incentive Stock Option

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

               (B) granted to any other Employee, 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

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

               (B) granted to any other Service Provider, the per Share
          exercise price shall be no less than 85% of the Fair Market Value per
          Share on the date of grant.

                                      -5-
<PAGE>

          (iii) Notwithstanding the foregoing, Options may be granted with a
     per Share exercise price other than as required above pursuant to a merger
     or other corporate transaction.

     (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). Such consideration may consist 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 such Option shall be exercised, (5) consideration received by the
Company under a cashless exercise program implemented by the Company in
connection with the Plan, or (6) 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 Shareholder. Any Option granted
hereunder shall be exercisable according to the terms hereof at such times and
under such conditions as determined by the Administrator and set forth in the
Option Agreement. 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. Unless the
Administrator provides otherwise, vesting of Options granted hereunder to
Officers and Directors 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 Shares, 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.

     Exercise of an Option in any manner shall result in a decrease in 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, such Optionee may exercise his or her Option within such
period of time as is specified in the Option Agreement (of at least thirty (30)
days) to the extent that the Option is vested

                                      -6-
<PAGE>

on the date of termination (but in no event later than the expiration of the
term of the 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 (of
at least six (6) months) 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 (of at least six (6) months) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance. 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 the
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan. 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.

     10. Non-Transferability of Options and Stock Purchase Rights. The Options
and Stock Purchase Rights 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. 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 of the terms, conditions and restrictions related to
the offer, including the number of Shares that such person shall be entitled to
purchase, the price to be paid, and the time within which such person must
accept such offer. The terms of the

                                      -7-
<PAGE>

offer shall comply in all respects with Section 260.140.42 of Title 10 of the
California Code of Regulations. 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 such rate as the Administrator may determine.
Except with respect to Shares purchased by Officers, Directors and Consultants,
the repurchase option shall in no case lapse at a rate of less than 20% per
year over five (5) years from the date of purchase.

     (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 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 shall 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 12 of the
Plan.

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

     (a) Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of shares of Stock covered by each
outstanding Option or Stock Purchase Right, and the number of shares of 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, as well as the price per share of 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 Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Stock, or any other increase or decrease in the number
of issued shares of Stock effected without receipt of consideration by the
Company. The 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 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 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 or Stock Purchase Right until

                                      -8-
<PAGE>

fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option or Stock Purchase
Right 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 or Stock Purchase Right 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 or Stock Purchase Right 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 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, the Optionee shall fully vest in and have the right to exercise
the Option or Stock Purchase Right as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an
Option or Stock Purchase Right 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 or Stock Purchase Right shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option or Stock
Purchase Right shall terminate upon the expiration of such period. 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
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 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 Stock of the successor corporation or its Parent equal in
fair market value to the per share consideration received by holders of Stock
in the merger or sale of assets.

     13. Time of Granting Options and Stock Purchase Rights. The date of grant
of an Option or Stock Purchase Right shall, for all purposes, be the date on
which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Service Provider to whom an
Option or Stock Purchase Right is so granted 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) Shareholder Approval. The Board shall obtain shareholder approval of
any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.

                                      -9-
<PAGE>

     (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.

     15. Conditions Upon Issuance of Shares.

     (a) Legal Compliance. 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 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, the Administrator 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.

     16. 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.

     17. Reservation of Shares. The Company, during the term of this Plan,
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     18. 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 degree and
manner required under Applicable Laws.

     19. Information to Optionees and Purchasers. The Company shall provide to
each Optionee and to each individual who acquires Shares pursuant to the Plan,
not less frequently than annually during the period such Optionee or purchaser
has one or more Options or Stock Purchase Rights outstanding, and, in the case
of an individual who acquires Shares pursuant to the Plan, during the period
such individual owns such Shares, copies of annual financial statements. 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.
