accordance with the Vesting Schedule set out in Section I and the applicable
provisions of this Option Agreement.

exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),

         (f)  Buyout Provisions.  The Company may at any time offer to buy out

compliance, for income tax purposes the Exercised Shares shall be considered
transferred to Optionee on the date the Option is exercised with respect to such
Exercised Shares.

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

                            d)  with the Company's consent, delivery of
Optionee's promissory note (the "Note") in the form attached hereto as Exhibit
                                                                       -------
C, in the amount of the aggregate Exercise Price of the Exercised Shares

                   ---------
federal rate" prescribed under the Code and its regulations at time of purchase,
and shall be secured by a pledge of the Shares purchased by the Note pursuant to
the Security Agreement.
<PAGE>

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

     6.  Term of Option.  This Option may be exercised only within the term set
         --------------
out in Section I, and may be exercised during such term only in accordance with
the terms of this Option Agreement.

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

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

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

         (c)  Merger or Asset Sale.  In the event of a merger of the Company
              --------------------
with or into another corporation, or the sale of substantially all of the assets
of the Company, an outstanding Option 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, Optionee shall fully vest in and have
the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Company shall notify Optionee in
writing or electronically that the Option shall be fully vested and exercisable
for a period
<PAGE>

of fifteen (15) days from the date of such notice, and the Option shall
terminate upon the expiration of such period. For the purposes of this
paragraph, the Option shall be considered assumed if, following the merger or
sale of assets, the option or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option immediately prior to the
merger or sale of assets, the consideration (whether stock, cash, or other
securities or property) received in the merger or sale of assets by holders of
Common Stock for each Share held on the effective date of the transaction (and
if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding Shares); provided,
however, that if such consideration received in the merger or sale of assets is
not solely common stock of the successor corporation or its Parent, the Company
may, with the consent of the successor corporation, provide for the
consideration to be received upon the exercise of the Option, for each Share of
Optioned Stock subject to the Option, to be solely common stock of the successor
corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

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

     9.  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.

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

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

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

     11. Entire Agreement; Governing Law.  This Option Agreement constitutes the
         -------------------------------
entire agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the Company
and Optionee with respect to the subject matter hereof, and may not be modified
adversely to Optionee's interest except by means of a writing signed by the
Company and Optionee.  This agreement is governed by the internal substantive
laws, but not the choice of law rules, of California.

     12. NO GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES AND AGREES
         ---------------------------------
 THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
 ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT
 THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES
 HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
 TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN
 DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
 SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
 NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
 OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
 CAUSE.
