Grant #______

                  [FORM OF INCENTIVE STOCK OPTION AGREEMENT]
                   ----------------------------------------

         This INCENTIVE STOCK OPTION AGREEMENT (this "Option Agreement"), dated
as of the [__] day of [_____], 1999 (the "Date of Grant"), by and between
PETsMART.com, Inc., a Delaware corporation (the "Company"), and [______] (the
"Optionee").

         Pursuant to the Company's 1999 Stock Plan (the "Plan"), the Board of
Directors of the Company (the "Board") or a committee appointed by the Board, as
the Administrator of the Plan, has determined that the Optionee is to be granted
an option (the "Option") to purchase shares of the Company's common stock, par
value $.001 per share (the "Common Stock"), on the terms and conditions set
forth herein, and hereby grants such Option. It is intended that the Option
constitute an "incentive stock option" within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"). In the event the Option
exceeds the $100,000 rule of Section 422(d), this Option shall be treated as a
Non-Qualified Stock Option.

         Any capitalized terms not defined herein shall have their respective
meanings set forth in the Plan.

         1. Number of Shares and Exercise Price. The Option entitles the
            -----------------------------------
Optionee to purchase [____] shares of the Company's Common Stock (the "Option
Shares") at a price of $.75 per share (the "Option Exercise Price"), which is at
least equal to the Fair Market Value of the Common Stock as of the Date of
Grant.

         2. Option Term. The term of the Option and of this Option Agreement
            -----------
(the "Option Term") shall commence on the Date of Grant and, unless the Option
is previously terminated pursuant to this Option Agreement, shall terminate upon
the expiration of ten (10) years from the Date of Grant. Upon expiration of the
Option Term, all rights of the Optionee hereunder shall terminate.

         3. Conditions of Exercise.
            ----------------------

             (a) This Option may be exercised in whole or in part at any time as
to 100% of the Option Shares, whether vested or unvested.

             (b) As a condition to exercising this Option for unvested Option
Shares, the Optionee shall be subject to the Company's right to repurchase such
shares, as set forth in Section 10 hereto .

<PAGE>

             (c) Except as otherwise provided herein, the right of the Optionee
to purchase Option Shares with respect to which this Option has become
exercisable may be exercised in whole or in part at any time or from time to
time prior to expiration of the Option Term. This Option may not be exercised
for a fraction of a share.

         4. Vesting Schedule.
            -----------------

             (a) So long as Optionee is employed by the Company and subject to
the provisions of the Plan and this Agreement, the Option shall vest

                 (i) as to twenty percent (20%) of the Option Shares, on the six
month anniversary of the Date of Grant,

                 (ii) as to twenty percent (20%) of the Option Shares, on the
first anniversary of the Date of Grant, and

                 (iii) as to the remaining sixty percent (60%) of the Option
Shares, 1/36th on the last date of each calendar month beginning on or after the
first anniversary of the Date of Grant, so that the Option Shares are fully
vested on or about the fourth anniversary of the Date of Grant.

             (b) In the event Optionee suffers an Involuntary Termination (as
defined in Section 25) of employment within six months following a Change of
Control (as defined in Section 25), fifty percent (50%) of the unvested portion
of the Option Shares shall vest in full.

             (c) In the event Optionee ceases to be employed by the Company
(unless Optionee (i) voluntarily terminates employment, or (ii) is terminated
for Cause (as defined in Section 25)), prior to the six month anniversary of the
Date of Grant, 20% of the Option Shares shall vest in full.

         5. Nontransferability of Option. The Option and this Option Agreement
            ----------------------------
shall not be transferable and, during the lifetime of Optionee, the Option may
be exercised only by Optionee. Without limiting the generality of the foregoing,
except as otherwise provided herein, the Option may not be assigned,
transferred, pledged or hypothecated in any way, shall not be assignable by
operation of law, and shall not be subject to execution, attachment or similar
process.

<PAGE>

Option

                 (ii) by means of a cashless exercise program adopted by the
Company in connection with the Plan,

                 (iii) in the form of shares of unrestricted Stock already owned

exercise of an option, have been owned by the optionee for more than six months
on the date of surrender, and (y) have an aggregate Fair Market Value on the
date of surrender equal to the aggregate Option Exercise Price of the Stock as
to which such Stock Option shall be exercised,

                 (iv) in the discretion of the Board, by delivery of a full
recourse promissory note (the "Note") (other than with respect to the par value
of the Shares, which shall be paid in cash or cash equivalents), the terms of
which are approved by the Board, or

                 (v) by any other means of exercise authorized from time to time
in the Plan and/or by the Board or a committee appointed by the Board.

         7. Company's Right of First Refusal. Before any Option Shares held by
            --------------------------------
Optionee or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Option Shares on the terms and conditions set forth in
this Section (the "Right of First Refusal").

             (a) Notice of Proposed Transfer. The Holder of the Option Shares
                 ---------------------------
shall deliver to the Company a written notice (the "Notice") stating: (i) the
Holder's bona fide intention to sell or otherwise transfer the Option Shares;
(ii) the name of each proposed purchaser or other transferee (each, a "Proposed
Transferee"); (iii) the number of Option Shares to be transferred to each
Proposed Transferee; and (iv) the bona fide cash price or other consideration
payable by each Proposed Transferee for which the Holder proposes to transfer
the Option Shares (the "Offered Price"), and the Holder shall offer the Option
Shares at the Offered Price to the Company or its assignee(s).

                                       3
<PAGE>

             (b) Exercise of Right of First Refusal. At any time within thirty
                 ----------------------------------
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Option Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

             (c) Purchase Price. The purchase price ("Purchase Price") for the
                 --------------
Option Shares purchased by the Company or its assignee(s) under this Section
shall be the Offered Price. If the Offered Price includes consideration other
than cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board in good faith.

             (d) Payment. Payment of the Purchase Price shall be made, at the
                 -------
option of the Company or its assignee(s), in cash or by check, by cancellation
of all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

             (e) Holder's Right to Transfer. If all of the Option Shares
                 --------------------------
proposed in the Notice to be transferred to one or more Proposed Transferees are
not purchased by the Company and/or its assignee(s) as provided in this Section
7, then the Holder may sell or otherwise transfer such Option Shares to the
Proposed Transferee(s) at the Offered Price or at a higher price, provided that
(i) such sale or other transfer is consummated within 120 days after the date of
the Notice, and (ii) any such sale or other transfer is effected in accordance
with any applicable securities laws and the Proposed Transferee(s) agrees in
writing that the provision of this Section 7 shall continue to apply to the
Option Shares in the hands of the Proposed Transferee(s). If the Option Shares
described in the Notice are not transferred to the Proposed Transferee(s) within
such 120-day period, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Option Shares held by the Holder may be sold or otherwise transferred.

             (f) Exception for Certain Family Transfers. Notwithstanding
                 --------------------------------------
anything to the contrary contained in this Section 7, the transfer of any or all
of the Option Shares during the Optionee's lifetime or on the Optionee's death
by will or intestacy to the Optionee's immediate family or a trust for the
benefit of the Optionee's immediate family shall be exempt from the provisions
of this Section 7. "Immediate Family" as used herein shall mean spouse, lineal
descendant or anteced-

                                       4
<PAGE>

ent, father, mother, brother or sister. In such case, the transferee or other
recipient shall receive and hold the Option Shares so transferred subject to the
provisions of this Section 7, and there shall be no further transfer of such
Option Shares except in accordance with the terms of this Section 7.

             (g) Termination of Right of First Refusal. The Right of First
                 -------------------------------------
Refusal shall terminate as to any Option Shares upon the consummation of an
initial underwritten public offering by the Company of its equity securities
pursuant to an effective registration statement filed under the Securities Act
of 1933, as amended (the "Securities Act").

         8. Effect of Termination of Employment. Upon the termination of
            -----------------------------------
Optionee's employment or service with the Company or any Subsidiary, the Option
shall immediately terminate as to any Option Shares that have not previously
vested as of the date of such termination (the "Termination Date"). Any portion
of the Option that has vested as of the Termination Date shall be exercisable in
whole or in part for a period of 90 days following the Termination Date;
provided, that in the event of termination by reason of Optionee's death or
Disability, such exercise period shall extend until the date that is twelve
months from the Termination Date. Upon expiration of such 90-day or twelve-month
period, as applicable, any unexercised portion of the Option shall terminate in
full.

         9. Investment Representation. The Optionee hereby represents and
            -------------------------
warrants to the Company that the Optionee, by reason of the Optionee's business
or financial experience (or the business or financial experience of the
Optionee's professional advisors who are unaffiliated with and who are not
compensated by the Company or any affiliate or selling agent of the Company,
directly or indirectly), has the capacity to protect the Optionee's own
interests in connection with the transactions contemplated under this Option
Agreement.

         10. Restricted Shares; Repurchase Option. Optionee may elect to
             ------------------------------------
exercise any portion of the Option prior to the Option Shares becoming vested
pursuant to Section 4 hereof. Upon exercise of the Option to purchase unvested
Option Shares, Optionee shall receive shares of stock, which until vested, shall
be restricted ("Restricted Shares"). The Restricted Shares shall be subject to
the following terms and conditions:

             (a) Transferability. The Optionee shall not transfer, assign,
encumber or otherwise dispose of any Restricted Shares, except (i) by will or by
the laws of descent or distribution or (ii) by transferring to the Company in
pledge as

                                       5
<PAGE>

security for payment of the Note. If the Optionee transfers any Restricted
Shares, this Section 10 shall apply to the transferee to the same extent as the
Optionee.

             (b) Exercise of Repurchase Option. The Company shall have the right
(but not the obligation) to repurchase the Restricted Shares during the sixty
(60) day period immediately following the later of (i) the date when the
Optionee ceases to be employed by the Company for any reason and (ii) the date
when such Restricted Shares were purchased by the Optionee, the executors or
administrators of the Optionee's estate or any person who has acquired this
Option directly from the Optionee by bequest, inheritance or beneficiary
designation (the "Repurchase Option").

             (c) Lapse of Repurchase Option. The Repurchase Option shall lapse
with respect to the Shares subject to this Option in accordance with the vesting
schedule (including any accelerated vesting) set forth in Section 4. In
addition, the Repurchase Option shall lapse and all of the remaining Restricted
Shares shall become vested at such time and in such events as Section 12 of the
Plan provides for vesting of Stock Purchase Rights.

             (d) Repurchase Option Price. If the Company exercises the
Repurchase Option, it shall pay the Optionee an amount equal to the Exercise
Price for each of the Restricted Shares being repurchased. Payment shall be made
in cash or cash equivalents or by canceling indebtedness to the Company incurred
by the Optionee in the purchase of the Restricted Shares.

             (e) Exercise of Repurchase Option. The Repurchase Option shall be
exercisable only by written notice delivered to the Optionee prior to the
expiration of the 60-day period specified in Subsection (b) above. The notice
shall set forth the date on which the repurchase is to be effected. Such date
shall not be more than 30 days after the date of the notice. The certificate(s)
representing the Restricted Shares to be repurchased shall, prior to the close
of business on the date specified for the repurchase, be delivered to the
Company properly endorsed for transfer. The Company shall, concurrently with the
receipt of such certificate(s), pay to the Optionee the purchase price
determined according to Subsection (d) above. The Repurchase Option shall
terminate with respect to any Restricted Shares for which it has not been timely
exercise pursuant to this Subsection (e).

             (f) Additional Shares of Substituted Securities. In the event of
the declaration of a stock dividend, the declaration of an extraordinary
dividend payable in a form other than stock, a spin-off, a stock split, an
adjustment in conversion ratio, a recapitalization or a similar transaction
affect the Company's

                                       6
<PAGE>

outstanding securities without receipt of consideration, any new, substituted or
additional securities or other property (including money paid other than as an
ordinary cash dividend) which are by reason of such transaction distributed with
respect to any Restricted Shares or into which such Restricted Shares thereby
become convertible shall immediately be subject to the Repurchase Option.
Appropriate adjustments to reflect the distribution of such securities or
property shall be made to the number and/or class of Restricted Shares.
Appropriate adjustments shall also, after each such transaction, be made to the
price per share to be paid upon the exercise of the Repurchase Option in order
to reflect any change in the Company's outstanding securities effected without
receipt of consideration therefor; provided, however, that the aggregate
purchase price payable for the Restricted Shares shall remain the same.

             (g) Termination of Rights as Stockholder. If the Company makes
available, at the time and place and in the amount and form provided in this
Agreement, the consideration for the Restricted Shares to be repurchased in
accordance with this Section 10, then after such time the person from whom such
Restricted Shares are to be repurchased shall no longer have any rights as a
holder of such Restricted Shares (other than the right to receive payment of
such consideration in accordance with this Agreement). Such Restricted Shares
shall be deemed to have been repurchased in accordance with the applicable
provisions hereof, whether or not the certificate(s) therefor have been
delivered as required by this Agreement.

             (h) Escrow. Upon issuance, if requested by the Company, the
certificates for Restricted Shares shall be deposited in escrow with the Company
to be held in accordance with the provisions of this Agreement. Any new,
substituted or additional securities or other property described in Subsection
(f) above shall immediately be delivered to the Company to be held in escrow,
but only to the extent the Shares are at the time Restricted Shares. All regular
cash dividends on Restricted Shares (or other securities at the time held in
escrow) shall be paid directly to the Optionee and shall not be held in escrow.
Restricted Shares, together with any other assets or securities held in escrow
hereunder, shall be (i) surrendered to the Company for repurchase and
cancellation upon the Company's exercise of its Repurchase Option or (ii)
released from escrow upon the Optionee's request to the extent the Shares are no
longer Restricted Shares (but not more frequently than once every six months).

                 ----------------------------
exercisable to any extent, and the Company shall not be obligated to transfer
any Option Shares to the Optionee upon exercise of such Option, if such
exercise, in the opinion of counsel for the Company, would violate the
Securities Act (or any other federal or state statutes having similar
requirements as may be in effect at that time). Further, the Company may require
as a condition of transfer of any Option Shares pursuant to any exercise of the
Option that the Optionee furnish a written representation that he or she is
purchasing or acquiring the Option Shares for investment and not with a view to
resale or distribution to the public. The Optionee hereby represents and
warrants that he or she understands that the Option Shares are "restricted
securities," as defined in Rule 144 under the Securities Act, and that any
resale of the Option Shares must be in compliance with the registration
requirements of the Securities Act, or an exemption therefrom, and with the
requirements of California "Blue Sky" law. Each certificate representing Option
Shares shall bear the legends set forth below and with any other legends that
may be required by the Company or by any Federal or state securities laws:

         ABSENCE OF REGISTRATION OR AN EXEMPTION THEREFROM.

         THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
         RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY THE
         ISSUER OR ITS ASSIGNEES(S). SUCH TRANSFER RESTRICTIONS AND RIGHT OF
         FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES

Further, if the Company decides, in its sole discretion, that the listing or
qualification of the Option Shares under any securities or other applicable law
is necessary or desirable, the Option shall not be exercisable, in whole or in
part, unless and until such listing or qualification, or a consent or approval
with respect thereto, shall have been effected or obtained free of any
conditions not acceptable to the Company.

         13. No Obligation to Register Option Shares. The Company shall be under
             ---------------------------------------
no obligation to register the Option Shares pursuant to the Securities Act or
any other Federal or state securities laws.

transfer in trust (voting or other) or other disposition of, or creation of a
security interest in or lien on, any of the Option Shares by any holder thereof

not transfer any of said Option Shares on its books nor will any of said Option
Shares be entitled to vote, nor will any dividends be paid thereon, unless and

the Company. The foregoing restrictions are in addition to and not in lieu of
any other remedies, legal or equitable, available to enforce said provisions.

right to deduct any withholding amounts from any payment or transfer of any kind
otherwise due to the Optionee.

<PAGE>

         16. Failure to Enforce Not a Waiver. The failure of the Company to
             -------------------------------
enforce at any time any provision of this Option Agreement shall in no way be
construed to be a waiver of such provision or of any other provision hereof.

         17. Governing Law. This Option Agreement shall be governed by and
             -------------
construed according to the laws of the State of California without regard to its
principles of conflict of laws.

         18. Incorporation of Plan. The Plan is hereby incorporated by reference

             ----------
time only by an instrument in writing signed by each of the parties hereto.

             -----------------------
Optionee's successors in interest shall have any rights as a stockholder of the
Company with respect to any shares of Common Stock subject to the Option until
the date of issuance of a stock certificate for such shares of Common Stock.

         21. Section 83(b) Election. Optionee hereby acknowledges that he has
             ----------------------
been informed that, with respect to the exercise of the Option for Restricted
Shares, an election may be filed by the Optionee with the Internal Revenue
Service, within 30 days of the purchase of the Shares, electing pursuant to
Section 83(b) of the Code to be taxed currently on any difference between the
Option Exercise Price and Fair Market Value of the Shares on the date of
purchase.

             Optionee acknowledges that it is Optionee's sole responsibility and
not the Company's to file timely the election under section 83(b) of the code,
even if Optionee requests the Company or its representative to make this filing
on Optionee's behalf.

         22. Agreement Not a Contract of Employment. Neither the Plan, the
             --------------------------------------
granting of the Option, this Option Agreement nor any other action taken
pursuant to the Plan shall constitute or be evidence of any agreement or
understanding, express or implied, that the Optionee has a right to continue to
provide services as an officer, director, employee, consultant or advisor of the
Company or any Parent Subsidiary or affiliate of the Company for any period of
time or at any specific rate of compensation.

         23. Authority of the Board. The Board, or a committee appointed by the
             ----------------------
Board, shall have full authority to interpret and construe the terms of the Plan
and this Option Agreement. The determination of the Board, or a committee
appointed by the Board, as to any such matter of interpretation or construction
shall be final, binding and conclusive.

         24. Market Stand-Off. Optionee agrees that, if so requested by the
             ----------------
Company or any representative of the underwriter (the "Managing Underwriter") in
connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. Such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act. The Company may impose

Grant #______

                 [FORM OF NONQUALIFIED STOCK OPTION AGREEMENT]
                  -------------------------------------------

          This NONQUALIFIED STOCK OPTION AGREEMENT (this "Option Agreement"),
dated as of the 28/th/ day of September, 1999 (the "Date of Grant"), by and
between PETsMART.com, Inc., a Delaware corporation (the "Company"), and [______]
(the "Optionee").

          Pursuant to the Company's 1999 Stock Plan (the "Plan"), the Board of
Directors of the Company (the "Board") or a committee appointed by the Board, as
the Administrator of the Plan, has determined that the Optionee is to be granted
an option (the "Option") to purchase shares of the Company's common stock, par
value $.001 per share (the "Common Stock"), on the terms and conditions set
forth herein, and hereby grants such Option. It is intended that the Option
constitute a "nonqualified stock option" and not an "incentive stock option"
within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code").

          Any capitalized terms not defined herein shall have their respective
meanings set forth in the Plan.

          1.   Number of Shares and Exercise Price. The Option entitles the
               -----------------------------------
Optionee to purchase [____] shares of the Company's Common Stock (the "Option
Shares") at a price of $.75 per share (the "Option Exercise Price").

          2.   Option Term.  The term of the Option and of this Option Agreement
               -----------
(the "Option Term") shall commence on the Date of Grant and, unless the Option
is previously terminated pursuant to this Option Agreement, shall terminate upon
the expiration of ten (10) years from the Date of Grant. Upon expiration of the
Option Term, all rights of the Optionee hereunder shall terminate.

          3.   Conditions of Exercise.
               ----------------------
               (a)  Subject to the provisions of the Plan and this Agreement,
the Option shall vest and become exercisable

                    (i)   as to twenty percent (20%) of the Option Shares, on
the Date of Grant,

                    (ii)  as to twenty percent (20%) of the Option Shares, on
the first anniversary of the Date of Grant,
<PAGE>

                    (iii) as to the remaining sixty percent (60%) of the Option
Shares, 1/36th on the last date of each calendar month beginning on or after the
first anniversary of the Date of Grant, so that the Option Shares are fully
vested on or about the fourth anniversary of the Date of Grant.

               (b)  Except as otherwise provided herein, the right of the
Optionee to purchase Option Shares with respect to which this Option has become
exercisable may be exercised in whole or in part at any time or from time to
time prior to expiration of the Option Term.

          4.   Nontransferability of Option and Option Shares. The Option and
               ----------------------------------------------
this Option Agreement shall not be transferable and, during the lifetime of
Optionee, the Option may be exercised only by Optionee. Without limiting the
generality of the foregoing, except as otherwise provided herein, the Option may
not be assigned, transferred, pledged or hypothecated in any way, shall not be
assignable by operation of law, and shall not be subject to execution,
attachment or similar process.

          5.   Method of Exercise of Option. The Option may be exercised by
               ----------------------------
means of written notice of exercise to the Company specifying the number of
Option Shares to be purchased, accompanied by payment in full of the aggregate
Option Exercise Price and any applicable withholding taxes (i) in cash or by
check, (ii) by means of a cashless exercise program adopted by the Company in
connection with the Plan, (iii) in the form of unrestricted Stock already owned
by the Optionee which, (x) in the case of unrestricted Stock 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 an aggregate Fair Market Value on the
date of surrender equal to the aggregate Option Exercise Price of the Stock as
to which such Stock Option shall be exercised, or (iv) by any other means of
exercise authorized from time to time in the Plan and/or by the Board or a
committee appointed by the Board.

          6.   Company's Right of First Refusal. Before any Option Shares held
               --------------------------------
by Optionee or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Option Shares on the terms and conditions set forth in
this Section (the "Right of First Refusal").

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

                                       2
<PAGE>

(ii) the name of each proposed purchaser or other transferee (each, a "Proposed
Transferee"); (iii) the number of Option Shares to be transferred to each
Proposed Transferee; and (iv) the bona fide cash price or other consideration
payable by each Proposed Transferee for which the Holder proposes to transfer
the Option Shares (the "Offered Price"), and the Holder shall offer the Option
Shares at the Offered Price to the Company or its assignee(s).

               (b)  Exercise of Right of First Refusal. At any time within
                    ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Option Shares proposed to be transferred to any one or more of
the Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

               (c)  Purchase Price. The purchase price ("Purchase Price") for
                    --------------
the Option Shares purchased by the Company or its assignee(s) under this Section
shall be the Offered Price.  If the Offered Price includes consideration other
than cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board in good faith.

               (d)  Payment. Payment of the Purchase Price shall be made, at the
                    -------
option of the Company or its assignee(s), in cash or by check, by cancellation
of all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

               (e)  Holder's Right to Transfer. If all of the Option Shares
                    --------------------------
proposed in the Notice to be transferred to one or more Proposed Transferees are
not purchased by the Company and/or its assignee(s) as provided in this Section
6, then the Holder may sell or otherwise transfer such Option Shares to the
Proposed Transferee(s) at the Offered Price or at a higher price, provided that
such sale or other transfer is consummated within 120 days after the date of the
Notice, and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee(s)
agrees in writing that the provision of this Section 6 shall continue to apply
to the Option Shares in the hands of the Proposed Transferee(s). If the Option
Shares described in the Notice are not transferred to the Proposed Transferee(s)
within such 120-day period, a new Notice shall be given to the Company, and the
Company and/or its assignees shall again be offered the Right of First Refusal
before any Option Shares held by the Holder may be sold or otherwise
transferred.

               (f)  Exception for Certain Family Transfers. Notwithstanding
                    --------------------------------------
anything to the contrary contained in this Section 6, the transfer of any or all
of the Option Shares during the Optionee's lifetime or on the Optionee's death
by will or intestacy to the Optionee's immediate family or a trust for the
benefit of the Optionee's immediate family shall be exempt from the provisions
of this Section 6. "Immediate Family" as used herein shall mean spouse, lineal
descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Option Shares so
transferred subject to the provisions of this Section 6, and there shall be no
further transfer of such Option Shares except in accordance with the terms of
this Section 6.

               (g)  Termination of Right of First Refusal. The Right of First
                    -------------------------------------
Refusal shall terminate as to any Option Shares upon the consummation of an
initial underwritten public offering by the Company of its equity securities
pursuant to an effective registration statement filed under the Securities Act
of 1933, as amended (the "Securities Act").

          7.   Effect of Termination of Service. Upon the termination of
               --------------------------------
Optionee's service with the Company or any Parent or Subsidiary, the Option
shall immediately terminate as to any Option Shares that have not previously
vested as of the date of such termination (the "Termination Date"). Any portion
of the Option that has vested as of the Termination Date shall be exercisable in
whole or in part for a period of 90 days following the Termination Date;
provided, however, that in the event of termination by reason of Optionee's
--------  -------
death or Disability, such exercise period shall extend until the date that is
twelve months from the Termination Date. Upon expiration of such 90-day or
twelve-month period, as applicable, any unexercised portion of the Option shall
terminate in full.

          8.   Investment Representation. The Optionee hereby represents and
               -------------------------
warrants to the Company that the Optionee, by reason of the Optionee's business
or financial experience (or the business or financial experience of the
Optionee's professional advisors who are unaffiliated with and who are not
compensated by the Company or any affiliate or selling agent of the Company,
directly or indirectly), has the capacity to protect the Optionee's own
interests in connection with the transactions contemplated under this Option
Agreement.

          10.  Securities Laws Requirements. The Option shall not be
               ----------------------------
exercisable to any extent, and the Company shall not be obligated to transfer
any Option Shares to the Optionee upon exercise of such Option, if such
exercise, in the opinion of counsel for the Company, would violate the
Securities Act (or any other federal or state statutes having similar
requirements as may be in effect at that time). Further, the Company may require
as a condition of transfer of any Option Shares pursuant to any exercise of the
Option that the Optionee furnish a written representation that he or she is
purchasing or acquiring the Option Shares for investment and not with a view to
resale or distribution to the public. The Optionee hereby represents and
warrants that he or she understands that the Option Shares are "restricted
securities," as defined in Rule 144 under the Securities Act, and that any
resale of the Option Shares must be in compliance with the registration
requirements of the Securities Act, or an exemption therefrom, and with the
requirements of California "Blue Sky" law. Each certificate representing Option
Shares shall bear the legends set forth below and with any other legends that
may be required by the Company or by any Federal or state securities laws:

                                       5
<PAGE>

          THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE RESTRICTED SECURITIES
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES
          THEREUNDER, AND MAY NOT BE SOLD, OFFERED FOR SALE OR OTHERWISE
          TRANSFERRED IN THE ABSENCE OF REGISTRATION OR AN EXEMPTION THEREFROM.

          THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY THE
          ISSUER OR ITS ASSIGNEES(S). SUCH TRANSFER RESTRICTIONS AND RIGHT OF
          FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES

Further, if the Company decides, in its sole discretion, that the listing or
qualification of the Option Shares under any securities or other applicable law
is necessary or desirable, the Option shall not be exercisable, in whole or in
part, unless and until such listing or qualification, or a consent or approval
with respect thereto, shall have been effected or obtained free of any
conditions not acceptable to the Company.

          11.  No Obligation to Register Option Shares. The Company shall be
               ---------------------------------------
under no obligation to register the Option Shares pursuant to the Securities Act
or any other Federal or state securities laws.

          12.  Protections Against Violations of Agreement. No purported sale,
               -------------------------------------------
assignment, mortgage, hypothecation, transfer, pledge, encumbrance, gift,
transfer in trust (voting or other) or other disposition of, or creation of a
security interest in or lien on, any of the Option Shares by any holder thereof
in violation of the provisions of this Agreement or the Certificate of
Incorporation or the Bylaws of the Company, will be valid, and the Company will
not transfer any of said Option Shares on its books nor will any of said Option
Shares be entitled to vote, nor will any dividends be paid thereon, unless and
until there has been full compliance with said provisions to the satisfaction of
the Company. The foregoing restrictions are in addition to and not in lieu of
any other remedies, legal or equitable, available to enforce said provisions.

          13.  Withholding Requirements. The Company's obligations under this
               ------------------------
Option Agreement shall be subject to all applicable tax and other withholding
requirements, and the Company shall, to the extent permitted by law, have the
right to deduct any withholding amounts from any payment or transfer of any kind
otherwise due to the Optionee.

<PAGE>

          14.  Failure to Enforce Not a Waiver. The failure of the Company to
               -------------------------------
enforce at any time any provision of this Option Agreement shall in no way be
construed to be a waiver of such provision or of any other provision hereof.

          15.  Governing Law. This Option Agreement shall be governed by and
               -------------
construed according to the laws of the State of California without regard to its
principles of conflict of laws.

          16.  Incorporation of Plan. The Plan is hereby incorporated by
               ---------------------
reference and made a part hereof, and the Option and this Option Agreement shall
be subject to all terms and conditions of the Plan.

          17.  Amendments.  This Option Agreement may be amended or modified at
               ----------
any time only by an instrument in writing signed by each of the parties hereto.

          18.  Rights as a Stockholder. Neither the Optionee nor any of the
               -----------------------
Optionee's successors in interest shall have any rights as a stockholder of the
Company with respect to any shares of Common Stock subject to the Option until
the date of issuance of a stock certificate for such shares of Common Stock.

          19.  Agreement Not a Contract of Employment. Neither the Plan, the
               --------------------------------------
granting of the Option, this Option Agreement nor any other action taken
pursuant to the Plan shall constitute or be evidence of any agreement or
understanding, express or implied, that the Optionee has a right to continue to
provide services as an officer, director, employee, consultant or advisor of the
Company or any Parent Subsidiary or affiliate of the Company for any period of
time or at any specific rate of compensation.

          20.  Authority of the Board. The Board, or a committee appointed by
               ----------------------
the Board, shall have full authority to interpret and construe the terms of the
Plan and this Option Agreement. The determination of the Board, or a committee
appointed by the Board, as to any such matter of interpretation or construction
shall be final, binding and conclusive.

          21.  Market Stand-Off. Optionee agrees that, if so requested by the
               ----------------
Company or any representative of the underwriter (the "Managing Underwriter") in
connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as

                                       7
<PAGE>

may be requested in writing by the Managing Underwriter and agreed to in writing
by the Company) (the "Market Standoff Period") following the effective date of a
registration statement of the Company filed under the Securities Act. Such
restriction shall apply only to the first registration statement of the Company
to become effective under the Securities Act that includes securities to be sold
on behalf of the Company to the public in an underwritten public offering under
the Securities Act. The Company may impose stop-transfer instructions with
respect to securities subject to the foregoing restrictions until the end of
such Market Standoff Period.

          IN WITNESS WHEREOF, the parties hereto have executed and delivered
this Option Agreement on the day and year first above written.
