stock bonus under its 1999 Equity Incentive Plan (the “Plan”) for the number of

be adjusted from time to time for Capitalization Adjustments, as provided in the
Plan.

        3.    SECURITIES LAW COMPLIANCE. You may not be issued any shares under

Act or (ii) the Company has determined that such issuance would be exempt from

with other applicable laws and regulations governing the Award, and you will not
receive such shares if the Company determines that such receipt would not be in
material compliance with such laws and regulations.

        4.    RESTRICTIVE LEGENDS. The shares issued under your Award shall be
endorsed with appropriate legends determined by the Company, if any.

        5.    AWARD NOT A SERVICE CONTRACT. Your Award is not an employment or
service contract, and nothing in your Award shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company

employment. In addition, nothing in your Award shall obligate the Company or an
Affiliate, their respective shareholders, boards of directors, Officers or

SCIENTIFIC LEARNING CORPORATION1999
EQUITY INCENTIVE PLAN

STOCK OPTION AGREEMENT(INCENTIVE
STOCK OPTION OR NONSTATUTORY STOCK OPTION)

        Pursuant to your Notice of Grant of Stock Options (“Grant Notice”) and
this Stock Option Agreement, Scientific Learning Corporation (the “Company”) has
granted you an option under its 1999 Equity Incentive Plan (the “Plan”) to
purchase the number of shares of the Company’s Common Stock indicated in your
Grant Notice at the exercise price indicated in your Grant Notice. Defined terms
not explicitly defined in this Stock Option Agreement but defined in the Plan
shall have the same definitions as in the Plan.

        The details of your option are as follows:

        1.    VESTING. Subject to the limitations contained herein, your option
will vest as provided in your Grant Notice, provided that vesting will cease
upon the termination of your Continuous Service.

        2.    NUMBER OF SHARES AND EXERCISE PRICE. The number of shares of
Common Stock subject to your option and your exercise price per share referenced
in your Grant Notice may be adjusted from time to time for Capitalization
Adjustments, as 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.

1.

--------------------------------------------------------------------------------

        4.    METHOD OF PAYMENT. Payment of the exercise price is due in full
upon exercise of 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.

        6.    SECURITIES LAW COMPLIANCE. Notwithstanding anything to the
contrary contained herein, 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. You may not exercise your option before the commencement of
its term or after its term expires. The term of your option commences on the
Date of Grant and expires upon the earliest of 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 (12) months after the termination of your
Continuous Service due to your Disability;

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

                (d)     the Expiration Date indicated in your Grant Notice; or

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

2.

--------------------------------------------------------------------------------

        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.

3.

--------------------------------------------------------------------------------

        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.
