the Plan.


The
details of your option are as follows:


1.VESTING.

provided in the Plan.


3.EXERCISE
PRIOR TO VESTING (EARLY EXERCISE). If permitted in           your Grant
Notice (i.e., Schedule A indicates that Early Exercise of           your
option is permitted) and subject to the provisions of your option, you may
          elect at any time that is both (i) during the period of your Continuous Service
          and (ii) during the term of your option, to exercise all or part of your
option,           including the nonvested portion of your option; provided, however,
that:


(a)           a
partial exercise of your option shall be deemed to cover first vested shares           of
Common Stock and then the earliest vesting installment of unvested shares of
          Common Stock;


(b)           any
shares of Common Stock so purchased from installments that have not vested           as
of the date of exercise shall be subject to the purchase option in favor of           the
Company as described in the Companys form of Early Exercise Stock
          Purchase Agreement;


(c)           you
shall enter into the Companys form of Early Exercise Stock Purchase
          Agreement with a vesting schedule that will result in the same vesting as if no
          early exercise had occurred; and


(d)           if
your option is an incentive stock option, then, as provided in the Plan, to           the
extent that the aggregate Fair Market Value (determined at the time of           grant)
of the shares of Common Stock with respect to which your option plus all           other
incentive stock options you hold are exercisable for the first time by you
          during any calendar year (under all plans of the Company and its Affiliates)
          exceeds one hundred thousand dollars ($100,000), your option(s) or portions
          thereof that exceed such limit (according to the order in which they were
          granted) shall be treated as nonstatutory stock options.

all or any part of your option. You may elect to make payment of the           exercise
price by one or more of the following:


(a)           by
cash or check; or


(b)           in
the Companys sole discretion at the time your option is exercised and
          provided that at the time of exercise the Common Stock is publicly traded and
          quoted regularly in The Wall Street Journal,pursuant to a program
          developed under Regulation T as promulgated by the Federal Reserve Board that,
          prior to the issuance of Common Stock, results in either the receipt of cash
(or           check) by the Company or the receipt of irrevocable instructions to pay the
          aggregate exercise price to the Company from the sales proceeds.


5.WHOLE
SHARES. You may exercise your option only for whole shares of           Common Stock.

you may not exercise your option unless the shares of Common           Stock issuable
upon such exercise are then registered under the Securities Act           or, if such
shares of Common Stock are not then so registered, the Company has           determined
that such exercise and issuance would be exempt from the registration
          requirements of the Securities Act. The exercise of your option must also
comply           with other applicable laws and regulations governing your option, and
you may           not exercise your option if the Company determines that such exercise
would not           be in material compliance with such laws and regulations.


7.TERM.

its term expires. The term of your option commences on the Date of           Grant and
expires upon the earliestof the following:


(a)           three
(3) months after the termination of your Continuous Service for any reason
          other than Disability or death, provided that if during any part of such three-
          (3-) month period you may not exercise your option solely because of the
          condition set forth in the preceding paragraph relating to Securities Law
          Compliance, your option shall not expire until the earlier of the
          Expiration Date or until it shall have been exercisable for an aggregate period
          of three (3) months after the termination of your Continuous Service;


(b)           twelve

          Disability;


(c)           twelve
(12) months after your death if you die either during your Continuous           Service;

(e)           the
day before the tenth (10th) anniversary of the Date of Grant.

|If
your option is an incentive stock option, note that, to obtain the federal income tax
advantages associated with an incentive stock option, the Code requires that
at all times beginning on the date of grant of your option and ending on the day three
(3) months before the date of your options exercise, you must be an employee of the
Company or an Affiliate, except in the event of your death or Disability. The Company has
provided for extended exercisability of your option under certain circumstances for your
benefit but cannot guarantee that your option will necessarily be treated as an incentive
stock option if you continue to provide services to the Company or an Affiliate as
a Consultant or Director after your employment terminates or if you otherwise exercise
your option more than three (3) months after the date your employment terminates.


8.EXERCISE.


(a)           You
may exercise the vested portion of your option (and the unvested portion of
          your option if your Grant Notice so permits) during its term by delivering a
          Notice of Exercise (in a form designated by the Company) together with the
          exercise price to the Secretary of the Company, or to such other person as the
          Company may designate, during regular business hours, together with such
          additional documents as the Company may then require.


(b)           By
exercising your option you agree that, as a condition to any exercise of your
          option, the Company may require you to enter into an arrangement providing for
          the payment by you to the Company of any tax withholding obligation of the
          Company arising by reason of (1) the exercise of your option, (2) the lapse of
          any substantial risk of forfeiture to which the shares of Common Stock are
          subject at the time of exercise, or (3) the disposition of shares of Common
          Stock acquired upon such exercise.


(c)           If
your option is an incentive stock option, by exercising your option you agree
          that you will notify the Company in writing within fifteen (15) days after the
          date of any disposition of any of the shares of the Common Stock issued upon
          exercise of your option that occurs within two (2) years after the date of your
          option grant or within one (1) year after such shares of Common Stock are
          transferred upon exercise of your option.


9.TRANSFERABILITY.
Your option is not transferable, except by will or by           the laws of descent and
distribution, and is exercisable during your life only           by you. Notwithstanding
the foregoing, by delivering written notice to the           Company, in a form
satisfactory to the Company, you may designate a third party           who, in the event
of your death, shall thereafter be entitled to exercise your           option.


10.    OPTION
NOT A SERVICE CONTRACT. Your option is not an employment or           service
contract, and nothing in your option shall be deemed to create in any           way
whatsoever any obligation on your part to continue in the employ of the           Company
or an Affiliate, or of the Company or an Affiliate to continue your           employment.
In addition, nothing in your option shall obligate the Company or an           Affiliate,
their respective stockholders, Boards of Directors, Officers or           Employees to
continue any relationship that you might have as a Director or           Consultant for
the Company or an Affiliate.

|11.WITHHOLDING
OBLIGATIONS.


(a)           At
the time you exercise your option, in whole or in part, or at any time
          thereafter as requested by the Company, you hereby authorize withholding from
          payroll and any other amounts payable to you, and otherwise agree to make
          adequate provision for (including by means of a cashless exercise          pursuant
to a program developed under Regulation T as promulgated by the Federal           Reserve
Board to the extent permitted by the Company), any sums required to           satisfy the
federal, state, local and foreign tax withholding obligations of the           Company or
an Affiliate, if any, which arise in connection with your option.


(b)           Upon
your request and subject to approval by the Company, in its sole           discretion,
and compliance with any applicable conditions or restrictions of           law, the
Company may withhold from fully vested shares of Common Stock otherwise
          issuable to you upon the exercise of your option a number of whole shares of
          Common Stock having a Fair Market Value, determined by the Company as of the
          date of exercise, not in excess of the minimum amount of tax required to be
          withheld by law. If the date of determination of any tax withholding obligation
          is deferred to a date later than the date of exercise of your option, share
          withholding pursuant to the preceding sentence shall not be permitted unless
you           make a proper and timely election under Section 83(b) of the Code,
covering           the aggregate number of shares of Common Stock acquired upon such
exercise with           respect to which such determination is otherwise deferred, to
accelerate the           determination of such tax withholding obligation to the date of
exercise of your           option. Notwithstanding the filing of such election, shares of
Common Stock           shall be withheld solely from fully vested shares of Common Stock
determined as           of the date of exercise of your option that are otherwise
issuable to you upon           such exercise. Any adverse consequences to you arising in
connection with such           share withholding procedure shall be your sole
responsibility.


(c)           You
may not exercise your option unless the tax withholding obligations of the
          Company and/or any Affiliate are satisfied. Accordingly, you may not be able to
          exercise your option when desired even though your option is vested, and the
          Company shall have no obligation to issue a certificate for such shares of
          Common Stock or release such shares of Common Stock from any escrow provided
for           herein.


12.NOTICES.
Any notices provided for in your option or the Plan shall be           given in writing
and shall be deemed effectively given upon receipt or, in the           case of notices
delivered by mail by the Company to you, five (5) days after           deposit in the
United States mail, postage prepaid, addressed to you at the last           address you
provided to the Company.


13.GOVERNING
PLAN DOCUMENT. Your option is subject to all the provisions of           the Plan,
the provisions of which are hereby made a part of your option, and is           further
subject to all interpretations, amendments, rules and regulations which           may
from time to time be promulgated and adopted pursuant to the Plan. In the           event
of any conflict between the provisions of your option and those of the           Plan,
the provisions of the Plan shall control.
