        1. Purposes of the Plan. The purposes of this Stock Plan are to attract
and retain the best available personnel for positions of substantial
responsibility, to provide additional incentive to Employees, Directors and
Consultants and to promote the success of the Company's business. Options
granted under the Plan may be Incentive Stock Options or Nonstatutory Stock
Options, as determined by the Administrator at the time of grant. Stock Purchase
Rights may also be granted under the Plan.

<PAGE>   4

Plan is 1,165,000 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;

                        (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;

                                      -4-
<PAGE>   5

                        (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 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

                                      -5-
<PAGE>   6

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.

                                      -6-
<PAGE>   7

                        (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 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.

                                      -7-
<PAGE>   8

        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 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

                                      -8-
<PAGE>   9

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 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.

                                      -9-
<PAGE>   10

        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 Common Stock covered by
each outstanding Option or Stock Purchase Right, and 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, 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 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 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 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
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

                                      -10-
<PAGE>   11

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 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.

        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.

                (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.

                                      -11-
<PAGE>   12

                (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 Share. 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.

                                  EGROUPS, INC.

                             1998 STOCK OPTION PLAN

                             STOCK OPTION AGREEMENT

        1. GRANT OF OPTION. eGroups, Inc., a Delaware corporation (the
"Company"), hereby grants to <<OPTIONEE>> ("Optionee") an option (the "Option")
to purchase a total number of shares of Common Stock (the "Shares") set forth in
the Notice of Stock Option Grant, at the exercise price per share set forth in
the Notice of Stock Option Grant (the "Exercise Price") subject to the terms,
definitions and provisions of the eGroups, Inc. 1998 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.

        If designated an Incentive Stock Option, this Option is intended to
qualify as an Incentive Stock Option as defined in Section 422 of the Code. If
the aggregate Fair Market Value of the shares with respect to which the Option
first becomes exercisable during any calendar year (under the Option and all
other Incentive Stock Options you hold) exceeds $100,000, the excess portion
will be treated as a nonstatutory stock option, unless the Internal Revenue
Service changes the rules and regulations governing the $100,000 limit for
Incentive Stock Options.

        2. EXERCISE OF OPTION. This Option shall be exercisable during its Term
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Section 9 of the Plan as follows:

               (a) RIGHT TO EXERCISE.

                      (i) This Option may be exercised in whole or in part at
any time after the Date of Grant, as to Shares which have not yet vested under
the vesting schedule indicated on the Notice of Stock Option Grant; provided,
however, that Optionee shall execute as a condition to such exercise of this
Option, the Early Exercise Notice and Restricted Stock Purchase Agreement
attached hereto as Exhibit A (the "Early Exercise Agreement"). If Optionee
chooses to exercise this Option solely as to Shares which have vested under the
vesting schedule indicated on the Notice of Stock Option Grant, Optionee shall
complete and execute the form of Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit B ( the "Exercise Agreement").
Notwithstanding the foregoing, the Company may in its discretion prescribe or
accept a different form of notice of exercise and/or stock purchase agreement if
such forms are otherwise consistent with this Agreement, the Plan and
then-applicable law.

                      (ii) This Option may not be exercised for a fraction of a
share.

                      (iii) In the event of Optionee's death, disability or
other termination of employment or consulting relationship, the exercisability
of the Option is governed by Sections 5, 6 and 7 below, subject to the
limitation contained in Section 2(a)(iv) below.

                      (iv) In no event may this Option be exercised after the
Expiration Date of this Option as set forth in the Notice of Stock Option Grant.

               (b) METHOD OF EXERCISE. This Option shall be exercisable by
execution and delivery of the Early Exercise Agreement or the Exercise
Agreement, whichever is applicable, or of any other

<PAGE>   2
written notice approved for such purpose by the Company 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 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
applicable law, including 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 Optionee on the date on which the
Option is exercised with respect to such Shares.

        3. METHOD OF PAYMENT. Payment of the Exercise Price shall be by any of
the following, or a combination thereof, at the election of Optionee:

               (a) cash;

               (b) check;

               (c) surrender of other shares of Common Stock of the Company
which (i) in the case of Shares acquired pursuant to the exercise of a Company
option, have been owned by Optionee for more than 6 months on the date of
surrender, and (ii) 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

               (d) if there is a public market for the Shares and they are
registered under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the Exercise Price.

               (e) subject to Section 153 of the Delaware General Corporation
Law, a promissory note in the form attached to this Agreement as Exhibit C, or
in any other form approved by the Company.

        4. 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 as promulgated by the
Federal Reserve Board. As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

        5. TERMINATION OF RELATIONSHIP. In the event of termination of
Optionee's Continuous Status as an Employee or Consultant, 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 forth in the
Notice of Stock Option Grant. To the extent that Optionee was not entitled to
exercise this Option at such Termination Date, or if Optionee does not exercise
this Option within the Termination Period, the Option shall terminate.

                                      -2-
<PAGE>   3
        6. DISABILITY OF OPTIONEE.

               (a) Notwithstanding the provisions of Section 5 above, in the
event of termination of Optionee's Continuous Status as an Employee or
Consultant as a result of his or her total and permanent disability (as defined
in Section 22(e)(3) of the Code), Optionee may, but only within twelve months
from the Termination Date (but in no event later than the Expiration Date set
forth in the Notice of Stock Option Grant and in Section 9 below), exercise this
Option to the extent he or she was entitled to exercise it at such Termination
Date. To the extent that Optionee was not entitled to exercise the Option on the
Termination Date, or if Optionee does not exercise such Option to the extent so
entitled within the time specified in this Section 6(a), the Option shall
terminate.

               (b) Notwithstanding the provisions of Section 5 above, in the
event of termination of Optionee's consulting relationship or Continuous Status
as an Employee as a result of a disability not constituting a total and
permanent disability (as set forth in Section 22(e)(3) of the Code), Optionee
may, but only within six months from the Termination Date (but in no event later
than the Expiration Date set forth in the Notice of Stock Option Grant and in
Section 9 below), exercise the Option to the extent Optionee was entitled to
exercise it as of such Termination Date; provided, however, that if this is an
Incentive Stock Option and Optionee fails to exercise this Incentive Stock
Option within three months from the Termination Date, this Option will cease to
qualify as an Incentive Stock Option (as defined in Section 422 of the Code) and
Optionee will be treated for federal income tax purposes as having received
ordinary income at the time of such exercise in an amount generally measured by
the difference between the Exercise Price for the Shares and the Fair Market
Value of the Shares on the date of exercise. To the extent that Optionee was not
entitled to exercise the Option at the Termination Date, or if Optionee does not
exercise such Option to the extent so entitled within the time specified in this
Section 6(b), the Option shall terminate.

        7. DEATH OF OPTIONEE. In the event of the death of Optionee (a) during
the Term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Status as an Employee or Consultant since the date of
grant of the Option, or (b) within 30 days after Optionee's Termination Date,
the Option may be exercised at any time within six months following the date of
death (but in no event later than the Expiration Date set forth in the Notice of
Stock Option Grant and in Section 9 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 of the right to exercise that had accrued at the Termination
Date.

        8. 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 him or her. The terms
of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of Optionee.

        9. TERM OF OPTION. This Option may be exercised only within the Term set
forth in the Notice of Stock Option Grant, subject to the limitations set forth
in Section 7 of the Plan.

        10. TAX CONSEQUENCES. Set forth below is a brief summary as of the date
of this Option of certain of the federal and California tax consequences of
exercise of this Option and disposition of the Shares under the laws in effect
as of the Date of Grant. 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.

                                      -3-
<PAGE>   4
               (a) EXERCISE OF INCENTIVE STOCK OPTION. If this Option qualifies
as an Incentive Stock Option, there will be no regular federal or California
income tax liability upon the exercise of the Option, although the excess, if
any, of the Fair Market Value of the Shares on the date of exercise over the
Exercise Price will be treated as an adjustment to the alternative minimum tax
for federal tax purposes and may subject Optionee to the alternative minimum tax
(up to a maximum of 28%) in the year of exercise.

               (b) EXERCISE OF NONSTATUTORY STOCK OPTION. If this Option does
not qualify as an Incentive Stock Option, there may be a regular federal income
tax liability and a California income tax liability upon the exercise of the
Option. 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, the Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

               (c) DISPOSITION OF SHARES. In the case of a Nonstatutory Stock
Option, 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 California income tax purposes. In the case of an Incentive Stock Option, 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 California income tax purposes. In either case, the
long-term capital gain will be taxed for federal income tax and alternative
minimum tax purposes at a maximum rate of 28% if the Shares are held more than
one year but less than 18 months after exercise and at 20% if the Shares are
held more than 18 months after exercise. If Shares purchased under an Incentive
Stock Option are disposed of within one year after exercise or within two years
after the Date of Grant, any gain realized on such 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 (i) the Fair Market
Value of the Shares on the date of exercise, or (ii) the sale price of the
Shares.

               (d) NOTICE OF DISQUALIFYING DISPOSITION OF INCENTIVE STOCK OPTION
SHARES. If the Option granted to Optionee herein is an Incentive Stock Option,
and if Optionee sells or otherwise disposes of any of the Shares acquired
pursuant to the Incentive Stock Option on or before the later of (i) the date
two years after the Date of Grant, or (ii) the date one year after the date of
exercise, Optionee shall immediately notify the Company in writing of such
disposition. Optionee acknowledges and agrees that he or she may be subject to
income tax withholding by the Company on the compensation income recognized by
Optionee from the early disposition by payment in cash or out of the current
earnings paid to Optionee.

        11. WITHHOLDING TAX OBLIGATIONS. Optionee understands that, upon
exercising a Nonstatutory Stock Option, he or she will recognize income for tax
purposes in an amount equal to the excess of the then Fair Market Value of the
Shares over the Exercise Price. However, the timing of this income recognition
may be deferred for up to six months if Optionee is subject to Section 16 of the
Exchange Act. If Optionee is an 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 equal to a percentage of this
compensation income. Additionally, Optionee may at some point be required to
satisfy tax withholding obligations with respect to the disqualifying
disposition of an Incentive Stock Option. Optionee shall satisfy his or her tax
withholding obligation arising upon the exercise of this Option by one or some
combination of the following methods: (a) by cash payment, (b) out of Optionee's
current compensation, (c) if permitted by the Administrator, in its discretion,
by surrendering to the Company Shares which (i) in the case of Shares previously
acquired from the Company, have been owned by Optionee for more than six months
on the date of surrender, and (ii) have a Fair Market Value on the date

                                      -4-
<PAGE>   5
of surrender equal to or greater than Optionee's marginal tax rate times the
ordinary income recognized, or (d) by electing to have the Company withhold from
the Shares to be issued upon exercise of the Option that number of Shares having
a Fair Market Value equal to the amount required to be withheld. For this
purpose, 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 (the "Tax
Date").

        If Optionee is subject to Section 16 of the Exchange Act (an "Insider"),
any surrender of previously owned Shares to satisfy tax withholding obligations
arising upon exercise of this Option must comply with the applicable provisions
of Rule 16b-3 promulgated under the Exchange Act ("Rule 16b-3").

        All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

               (a) the election must be made on or prior to the applicable Tax
Date;

               (b) once made, the election shall be irrevocable as to the
particular Shares of the Option as to which the election is made; and

               (c) all elections shall be subject to the consent or disapproval
of the Administrator.

        12. MARKET STANDOFF AGREEMENT. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Optionee agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any securities of the Company (other
than those included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed 180 days) from the effective date of such registration as may be
requested by the Company or such managing underwriters and to execute an
agreement reflecting the foregoing as may be requested by the underwriters at
the time of the Company's initial public offering.

        This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original and all of which together shall constitute one
document.

OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES
THAT NOTHING IN THIS AGREEMENT, NOR IN THE COMPANY'S STOCK OPTION PLAN WHICH IS
INCORPORATED HEREIN BY REFERENCE, SHALL CONFER UPON OPTIONEE ANY RIGHT WITH
RESPECT TO CONTINUATION OF EMPLOYMENT OR CONSULTANCY BY THE COMPANY, NOR SHALL
IT INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S EMPLOYMENT OR CONSULTANCY AT ANY TIME, WITH OR WITHOUT
CAUSE.

he or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof. Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option.
