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

         1.  Grant of Option. The Administrator hereby grants Optionee an Option
             ---------------
to purchase the number of Shares as set forth in the Notice of Grant, at the
exercise price per share set forth in the Notice of Grant (the "Exercise
Price"), subject to the terms and conditions of this Option Agreement.

         2.  Exercise of Option.
             ------------------

             (a)   Right to Exercise. This Option is exercisable during its term
                   -----------------
in accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of this Option Agreement. Unless the Administrator
provides otherwise, vesting of the Option shall be tolled during any unpaid
leave of absence. The Option may not be exercised for a fraction of a share.

             Shares issued upon exercise of the Option shall be issued in the
name of Optionee or, if requested by Optionee, in the name of Optionee and his
spouse. Until the Shares are issued (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company),
no right to vote or receive dividends or any other rights as a shareholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option. The Company shall issue (or cause to be issued) such Shares promptly
after the Option is exercised. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Shares are
issued, except as provided in Appendix 3 to this Option Agreement.
                              ----------

             Exercising the Option in any manner shall decrease the number of
Shares thereafter available for sale under the Option by the number of Shares as
to which the Option is exercised.

             (b)   Method of Exercise. This Option is exercisable by delivery of
                   ------------------
an exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
                                            ---------
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of this Option Agreement. The Exercise Notice shall
be completed by Optionee and delivered to the Administrator of the Company. The
Exercise Notice shall be accompanied by payment of the aggregate Exercise Price
as to all Exercised Shares. The Option shall be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.

             (c)   Method of Payment. Payment of the aggregate Exercise Price
                   -----------------
shall be by any of the following, or a combination thereof, at the election of
Optionee:

                   (i)      cash; or

                   (ii)     check; or

                   (iii)    consideration received by the Company under a
cashless exercise program implemented by the Company in connection with this
Option Agreement; or

                                      -2-

<PAGE>

              (iv) surrender of other Shares which (i) in the case 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.

        (d)   Termination of Relationship as a Service Provider. If Optionee
              -------------------------------------------------
ceases to be a Service Provider, other than upon Optionee's death or Disability,
Optionee may exercise his Option within such period of time as is specified in
the Notice of Grant 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 such
Option as set forth in the Notice of Grant). If, on the date of termination,
Optionee is not vested as to his entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Company. If, after
termination, Optionee does not exercise his Option within the time specified by
the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Company.

        (e)   Disability of Optionee. If Optionee ceases to be a Service
              ----------------------
Provider as a result of Optionee's Disability, Optionee may exercise his Option
within such period of time as is specified in the Notice of Grant 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 Notice of Grant). If,
on the date of termination, Optionee is not vested as to his entire Option, the
Shares covered by the unvested portion of Option shall revert to the Company.
If, after termination, Optionee does not exercise his Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Company.

        (f)   Death of Optionee. If Optionee dies while a Service Provider, the
              -----------------
Option may be exercised within such period of time as is specified in the Notice
of Grant (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by Optionee's estate or by a person who
acquires the right to exercise the Option by bequest or inheritance, but only to
the extent that the Option is vested on the date of death. If, at the time of
death, Optionee is not vested as to his entire Option, the Shares covered by the
unvested portion of the Option shall immediately revert to the Company. The
Option may be exercised by the executor or administrator of Optionee's estate
or, if none, by the person(s) entitled to exercise the Option under Optionee's
will or the laws of descent or distribution. If the Option is not so exercised
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Company.

        (g)   Buyout Provisions. The Administrator may at any time offer to buy
              -----------------
out the Option for a payment in cash or Shares based on such terms and
conditions as the Administrator shall establish and communicate to Optionee at
the time that such offer is made.

     3. Stock Subject to the Option Agreement. If the Option 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 by the Company;
provided, however, that Shares that have actually been issued under the Option
--------  -------
Agreement, upon exercise of the Option, shall not become available for future
distribution by the Company.

                                       -3-

<PAGE>

     4.  Limitations.
         -----------

         (a)  The Fair Market Value of the Shares shall be determined as of the
time the Option with respect to such Shares is granted.


         (b)  Neither the Option Agreement nor the Option shall confer upon
Optionee any right with respect to continuing Optionee's relationship as a
Service Provider with the Company, nor shall they interfere in any way with
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

     5.  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 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 the Notice of Grant, and may be exercised during such term only in
accordance with the terms of this Option Agreement.

     7.  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 SUBJECT TO THE OPTION.

         (a)  Exercising the Option. Optionee may incur regular federal income
              ---------------------
tax liability upon exercise of a NSO. Optionee will be treated as having
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 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 NSO Shares for at least
              ---------------------
one year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.

     8.  Amendment and Termination of the Option Agreement.
         -------------------------------------------------

         (a)  Effect of Amendment or Termination. No amendment, alteration,
              ----------------------------------
suspension or termination of the Option Agreement shall impair the rights of
Optionee, unless mutually agreed otherwise between the Administrator and
Optionee, which agreement must be in writing and signed by the Company and
Optionee.

                                       -4-

<PAGE>

     9.  Conditions Upon Issuance of Shares.
         ----------------------------------

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

         Assuming such 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.

         (b)  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.

     10. 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 under this Option Agreement, 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.

     11. Reservation of Shares. The Company, during the term of this Option
         ---------------------
Agreement, will at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of this Option Agreement.

     12. Entire Agreement; Governing Law. This Option Agreement constitutes the
         -------------------------------
entire agreement of the parties with respect to the subject matter hereof and
supersedes in its 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 Delaware.

     13. 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.

              (i)   to determine the Fair Market Value;

              (ii)  to select the Service Provider to whom the Option may be
granted hereunder;

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

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

              (v)   to determine the terms and conditions, not inconsistent with
the terms of the Option Agreement, of any Option granted hereunder. Such terms
and conditions include, but are not limited to, the Exercise Price, the date of
grant, the time or times when the Option may be exercised (which may be based on
performance criteria), any vesting acceleration or waiver of forfeiture
restrictions, and any restriction or limitation regarding the Option or the
shares of Common Stock relating thereto, based in each case on such factors as
the Administrator, in its sole discretion, shall determine;

              (vi)  to reduce the exercise price of the Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option shall have declined since the date the Option was granted;

              (vii) to institute an Option Exchange Program;

<PAGE>

          (viii) to construe and interpret the terms of the Option granted
pursuant to the Option Agreement;

          (ix)   to prescribe, amend and rescind rules and regulations relating
to the Option Agreement;

          (x) to modify or amend the Option (subject to the terms of the Option
Agreement), including the discretionary authority to extend the post-termination
exercisability period of the Option longer than is otherwise provided for in the
Option Agreement;

          (xi)   to allow Optionee to satisfy withholding tax obligations 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. 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. An election by Optionee to have Shares withheld for this
purpose shall be made in such form and under such conditions as the
Administrator may deem necessary or advisable;

          (xii)  to authorize any person to execute on behalf of the Company any
instrument required to effect the grant of an Option previously granted by the
Administrator;

          (xiii) to make all other determinations deemed necessary or advisable
for administering the Option Agreement.

     (c)  Effect of Administrator's Decision. The Administrator's decisions,
          ----------------------------------
determinations and interpretations shall be final and binding on Optionee.

                                   ----------

     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 the Option.

     (b) Dissolution or Liquidation. In the event of the proposed dissolution or
         --------------------------
liquidation of the Company, the Administrator shall notify Optionee as soon as
practicable prior to the effective date of such proposed transaction. The
Administrator in its discretion may provide for Optionee to have the right to
exercise his 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 Administrator may provide
that any Company repurchase option applicable to any Shares purchased upon
exercise of the 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, the 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 Administrator shall notify Optionee
in writing or electronically that the Option shall be fully vested and
exercisable for a period 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
--------  -------

<PAGE>

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.
