(whichever is applicable), as applicable, with such duties and responsibilities
as the Company, the Partnership or any Subsidiary (as applicable) shall from

Termination of Consultancy (each as defined in the Plan), all of the Unreleased
Shares (as defined below) shall thereupon be forfeited immediately and without
any further action by the Company (the "Forfeiture Restriction").

        3.2 Release of Shares from Restrictions.

                (a) Subject to Sections 3.1, 3.5, 3.6 and 4.4, each Share shall
        be released from the Forfeiture Restriction and the Transfer Restriction
        as indicated in Exhibit A to this Agreement.

                (b) Any of the Shares which, from time to time, have not yet
        been released from the Forfeiture Restriction and the Transfer
        Restriction are referred to herein as "Unreleased Shares."

                (c) Notwithstanding anything in this Agreement to the contrary,
        in the event of a Change of Control, or the death or Disability of the
        Holder, all of the Unreleased Shares shall cease to be subject to the
        Forfeiture Restriction or the Transfer Restriction.

        3.3 Legend. Certificates representing Shares issued pursuant to this
Agreement shall, until such Shares are released from the Forfeiture Restriction
and the Transfer Restriction and new certificates are issued therefor, bear the
following legend:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
        FORFEITURE AND CERTAIN RESTRICTIONS ON TRANSFERABILITY UNDER THE TERMS
        OF THAT CERTAIN RESTRICTED STOCK AGREEMENT BY AND BETWEEN ARDEN REALTY,
        INC. (THE "COMPANY"), ARDEN REALTY LIMITED PARTNERSHIP AND THE
        REGISTERED OWNER OF SUCH SHARES, AND SUCH SHARES MAY NOT BE, DIRECTLY OR

        OR OTHERWISE DISPOSED OF UNDER ANY CIRCUMSTANCES, EXCEPT PURSUANT TO THE
        PROVISIONS OF SUCH AGREEMENT."

        3.4 Issuance of Certificates for Vested Shares. Subject to Section 3.7,
upon the release of Shares from the Forfeiture Restriction and the Transfer
Restriction, the Company shall cause new certificates to be issued with respect
to such vested Shares and delivered to the Holder or his legal representative,
free from the legend provided for in Section 3.3. Such vested Shares shall cease
to be subject to the terms and conditions of this Agreement.

        3.5 Restrictions On New Shares. In the event that the Holder receives
any new or additional or different shares or securities which are attributable
to the Holder in his capacity as the registered owner of Shares then subject to
Forfeiture Restriction and the Transfer Restriction, such new or additional or

Agreement, the Company shall be entitled to require payment in cash or deduction
from other compensation payable to the Holder of any sums required by federal,
state or local tax law to be withheld with respect to the issuance, lapsing of
restrictions on or exercise of the Shares. The Board or the Committee may, in
their discretion, allow the Holder to deliver shares of Common Stock owned by
the Holder duly endorsed for transfer to the Company with an aggregate Fair
Market Value on the date of delivery equal to the statutory minimum sums to be
withheld. The Company shall not be obligated to deliver any new certificate
representing vested Shares to the Holder or his legal representative unless and
until the Holder or his legal representative shall have paid or otherwise
satisfied in full the amount of all federal, state and local taxes applicable to
the taxable income of the Holder resulting from the grant of the Shares or the
lapse or removal of the Forfeiture Restriction and the Transfer Restriction.

                                  ARTICLE IV.
                                  MISCELLANEOUS

        4.1 Unreleased Shares Not Transferable. Unless otherwise permitted by
the Committee pursuant to the Plan, no Unreleased Shares or any interest or
right therein or part thereof shall be liable for the debts, contracts or
engagements of the Holder or his successors in interest or shall be subject to
disposition by transfer, alienation, anticipation, pledge, encumbrance,
assignment or any other means whether such disposition be voluntary or
involuntary or by operation of law by judgment, levy, attachment, garnishment or
any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect (the
"Transfer Restriction"); provided, however, that this Section 4.1 shall not
prevent transfers by will or by applicable laws of descent and distribution. In
case of a permitted transfer, the transferee or other recipient shall receive
and hold the Shares so transferred subject to the provisions of this Agreement,
and there shall be no further transfer of such Shares except in accordance with
the terms of this Section. Any transferee shall acknowledge the same by signing

restrictions on transfer imposed by any applicable state and federal securities
laws.

stock pursuant to this Agreement prior to fulfillment of all of the following

        exchanges on which such class of stock is then listed; and

        withheld, under federal, state and local tax laws, with respect to the
        issuance of Shares and/or the lapse or removal of the Forfeiture
        Restriction and/or the Transfer Restriction; and

                (c) The lapse of such reasonable period of time as the Committee
        may from time to time establish for reasons of administrative
        convenience.

                                       5
<PAGE>

                (d) The completion of any registration or other qualification of
        such shares under any state or federal law or under rulings or
        regulations of the Securities and Exchange Commission or of any other
        governmental regulatory body, which the Committee shall, in its absolute
        discretion, deem necessary or advisable; and

                (e) The obtaining of any approval or other clearance from any
        state or federal governmental agency which the Committee shall, in its
        absolute discretion, determine to be necessary or advisable.

        4.3 Escrow.

                (a) Holder hereby authorizes and directs the Secretary of the
        Company, or such other person designated by the Company, to transfer the
        Unreleased Shares as to which the Forfeiture Option is effective from
        Holder to the Company.

                (b) To insure the availability for delivery of Holder's
        Unreleased Shares upon forfeiture pursuant to Section 3.1, Holder hereby
        appoints the Secretary, or any other person designated by the Company as
        escrow agent, as its attorney-in-fact to sell, assign and transfer unto
        the Company, such Unreleased Shares, if any, forfeited pursuant to the
        Forfeiture Option and shall, upon execution of this Agreement, deliver
        and deposit with the Secretary of the Company, or such other person
        designated by the Company, the share certificates representing the
        Unreleased Shares, together with the stock assignment duly endorsed in
        blank, attached hereto as Exhibit B. The Unreleased Shares and stock
        assignment shall be held by the Secretary in escrow, pursuant to the
        Joint Escrow Instructions of the Company and Holder attached as Exhibit
        C hereto, until the Forfeiture Restriction becomes effective as provided
        in Section 3.1, until such Unreleased Shares are vested, or until such
        time as this Agreement no longer is in effect. Upon vesting of the
        Unreleased Shares, the escrow agent shall promptly deliver to the Holder
        the certificate or certificates representing such Shares in the escrow
        agent's possession belonging to the Holder, and the escrow agent shall
        be discharged of all further obligations hereunder; provided, however,
        that the escrow agent shall nevertheless retain such certificate or
        certificates as escrow agent if so required pursuant to other
        restrictions imposed pursuant to this Agreement.

                (c) The Company, or its designee, shall not be liable for any
        act it may do or omit to do with respect to holding the Shares in escrow
        and while acting in good faith and in the exercise of its judgment.

        4.4 Ownership Limit and REIT Status. The Forfeiture Restriction and/or
the Transfer Restriction on the Shares shall not lapse if the lapsing of such
restrictions would likely result in any of the following:

                (a) a violation of the restrictions or limitations on ownership
        provided for from time to time under the terms of the organizational
        documents of the Company; or

                (b) income to the Company that could impair the Company's status
        as a real estate investment trust, within the meaning of Section 856
        through 860 of the Code.

the Company shall be addressed to the Company in care of its Secretary, and any
notice to be given to the Holder shall be addressed to him at the address given
beneath his signature hereto. By a notice given pursuant to this Section 4.5,
either party may hereafter designate a different address for notices to be given
to it or him. Any notice which is required to be given to the Holder shall, if
the Holder is then deceased, be given to the Holder's personal representative if
such representative has previously informed the Company of his status and
address by written notice under this Section 4.5. Any notice shall have been
deemed duly given when enclosed in a properly sealed envelope or wrapper
addressed as aforesaid, deposited (with postage prepaid) in a post office or
branch post office regularly maintained by the United States Postal Service.

        4.6 Rights as Stockholder. Except as otherwise provided herein, upon
delivery of the Shares to the escrow holder pursuant to Section 4.3, the Holder
shall have all the rights of a stockholder with respect to said shares, subject
to the restrictions herein, including the right to vote the shares and to
receive all dividends or other distributions paid or made with respect to the
Shares; provided, however, that any and all shares of Common Stock received by
the Holder with respect to such Shares as a result of stock dividends, stock
splits or any other form of recapitalization shall also be subject to the
Forfeiture Restriction and the Transfer Restriction until such restrictions on
the underlying Shares lapse or are removed pursuant to this Agreement.

        4.7 Titles. Titles are provided herein for convenience only and are not
to serve as a basis for interpretation or construction of this Agreement.

        4.8 Conformity to Securities Laws. The Holder acknowledges that the Plan
and this Agreement are intended to conform to the extent necessary with all
provisions of all applicable federal and state laws, rules and regulations
(including but not limited to, the Securities Act and the Exchange Act) and to
such approvals by any listing, regulatory or other governmental authority as
may, in the opinion of counsel for the Company, be necessary or advisable in
connection therewith. Notwithstanding anything herein to the contrary, this
Agreement shall be administered, and the Shares shall be issued, only in such a
manner as to conform to such laws, rules and regulations. To the extent
permitted by applicable law, the Plan, this Agreement and the Shares issued
hereunder shall be deemed amended to the extent necessary to conform to such
laws, rules and regulations.

        4.9 Limitations Applicable to Section 16 Persons and Performance-Based
Compensation. Notwithstanding any other provision of this Agreement, the Plan,
the Shares and this Agreement shall be subject to any additional limitations set
forth in any applicable exemptive rule under Section 16 of the Exchange Act
(including any amendment to Rule 16b-3) that are requirements for the
application of such exemptive rule. To the extent permitted by applicable law,
the Plan, this Agreement and the Shares issued hereunder shall be deemed amended
to the extent necessary to conform to such applicable exemptive rule.
Furthermore, notwithstanding any other provision of the Plan or this Agreement,
the Shares shall be subject to any additional limitations set forth in Section
162(m) of the Code (including any amendment to Section 162(m) of the Code) or
any regulations or rulings issued thereunder that are requirements for
qualification as performance-based compensation as described in Section
162(m)(4)(C) of the Code, and this Agreement shall be deemed amended to the
extent necessary to conform to such requirements unless the Committee shall have
determined that the Shares are not intended to so qualify.

                                    EXHIBIT A

                               VESTING PROVISIONS

        1. Capitalized terms used in this Exhibit A and not defined below shall
have the meanings given them in the Agreement to which this Exhibit A is
attached.

        2. Performance-Based Vesting.

               (a) Performance-Based Vesting. If the Company's Total Return to
Shareholders (as defined below) for a Measurement Period (as defined below) is
greater than either (i) ___% of the Morgan Stanley REIT Index (the "Morgan
Stanley Target") for such Measurement Period or (ii) ___% (together with the
Morgan Stanley Target for the applicable Measurement Period, the "Performance
Targets"), then ___% of the Unreleased Shares shall be released from the
Company's Repurchase Option on the applicable Performance Vesting Effective
Date. The Company's Total Return to Shareholders shall be calculated as soon as
practicable following the last day of each Measurement Period (each, a
"Calculation Date"). In the event the Company's Total Return to Shareholders for
a Measurement Period is not greater than either of the Performance Targets for
such Measurement Period, the Company's Total Return to Shareholders for such
Measurement Period shall be recalculated on each Calculation Date thereafter
after applying available Carryover Credits as described in paragraph (b) below.
Carryover Credits shall be applied to the Measurement Periods for which
recalculations are to be performed in the order such Measurement Periods
occurred. To the extent the Performance Targets have not been satisfied for one
or more Measurement Periods as of the final Calculation Date, all of the
Unreleased Shares shall be forfeited immediately following the final Calculation
Date and without any further action by the Company.

               (b) Total Return to Shareholders. For purposes of this Exhibit A,
the term "Total Return to Shareholders" for a Measurement Period means the sum
of (i) the total return on a share of the Company's Common Stock for the period
commencing on the first day of the Measurement Period and ending on the last day
of the Measurement Period, calculated as the quotient obtained by dividing (A)
the sum of (1) dividends per share plus (2) the difference between the Fair
Market Value of such share on the last day of the Measurement Period less the
Fair Market Value of such share on the first day of the Measurement Period,
divided by (B) the Fair Market Value of such share on the first day of the
Measurement Period, plus (ii) all available Carryover Credits; provided,
however, that a Carryover Credit may only be applied once in the calculation of
Total Return to Shareholders for all Measurement Periods.

               (c) Definition of Carryover Credit. For purposes of this Exhibit
A, the term "Carryover Credit" means, with respect with each Measurement Period,
the amount, if any, by which the Company's Total Return to Shareholders for such
Measurement Period is greater than the lower of the two Performance Targets for
such Measurement Period.

               (d) Definition of Measurement Period. For purposes of this
Exhibit A, the term "Measurement Period" means each of the twelve month periods
ending __________, 20__, 20__, 20__, 20__ and 20__.

                                      A-1
<PAGE>

               (e) Definition of Performance Vesting Effective Date. For
purposes of this Exhibit A, the term "Performance Vesting Effective Date" means,
with respect to each Measurement Period, the Calculation Date, if any, upon
which the Company's Total Return to Shareholders (as calculated pursuant to
paragraph (b) above) is determined by the Committee to be greater than either of
the Performance Targets for such Measurement Period. The Performance Vesting
Effective Date may be the same for one or more Measurement Periods.

               (f) Continued Service Condition. Unreleased Shares shall only be
released from the Company's Repurchase Option pursuant to this paragraph 2 if
Holder is an Employee, Director or Consultant of the Company or any of its
Subsidiaries on the applicable Performance Vesting Effective Date.

        3. Limit on Release of Shares. In no event will more than 100% of the
Unreleased Shares be released from the Company's Repurchase Option pursuant to
the provisions of this Exhibit A.

                         SCIENTIFIC LEARNING CORPORATION
                 1999 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

                         TERMINATION DATE: MAY 17, 2009

1.    PURPOSE.

      (a) The purpose of the 1999 Non-Employee Directors' Stock Option Plan (the
"Plan") is to provide a means by which each member of the Board of Directors of
Scientific Learning Corporation (the "Company") who is not at the time of grant
an employee of the Company or of any Affiliate of the Company, or a holder or
representative of the holder of 10% or more of the Company's capital stock (each
such person being hereafter referred to as a "Non-Employee Director") will be
given an opportunity to purchase stock of the Company.

      (b) The word "Affiliate" as used in the Plan means any parent corporation
or subsidiary corporation of the Company as those terms are defined in Sections
424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended
from time to time (the "Code").

      (c) The Company, by means of the Plan, seeks to retain the services of
persons now serving as Non-Employee Directors of the Company, to secure and
retain the services of persons capable of serving in such capacity, and to
provide incentives for such persons to exert maximum efforts for the success of
the Company.

2.    ADMINISTRATION.

      (a) The Board of Directors of the Company (the "Board") shall administer
the Plan unless and until the Board delegates administration to a committee, as
provided in subparagraph 2(b).

      (b) The Board may delegate administration of the Plan to a committee
composed of two (2) or more members of the Board (the "Committee"). If
administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed
by the Board, subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan.

                                       1.
<PAGE>

3.    SHARES SUBJECT TO THE PLAN.

      (a) Subject to the provisions of paragraph 10 relating to adjustments upon
changes in stock, the stock that may be sold pursuant to options granted under
the Plan shall not exceed in the aggregate Two Hundred Fifty Thousand (250,000)
shares of the Company's common stock. If any option granted under the Plan shall
for any reason expire or otherwise terminate without having been exercised in
full, the stock not purchased under such option shall again become available for
the Plan.

      (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

      (c) Notwithstanding any provision herein to the contrary, in the event the
Plan is not approved by holders of at least two-thirds of the Company's
outstanding common stock within twelve months of the date an option is first
granted hereunder following the October 2002 amendment of the Plan, then, unless
an exemption from qualification is available with respect to such grant that
does not require compliance with the provisions of 260.140.45 of the California
Code of Regulations, any option granted hereunder which (i) followed the October
2002 amendment of the Plan and (ii) was granted at a time when the total number
of securities issuable upon exercise of all outstanding options [exclusive of
rights described in Section 260.140.40 and warrants described in Sections
260.140.43 and 260.140.44 of the California Code of Regulations, and any
purchase plan or agreement as described in Section 260.140.42 of the California
Code of Regulations (provided that the purchase plan or agreement provides that
all securities will have a purchase price of 100% of the fair value, as
determined in accordance with Section 260.140.50 of the California Code of
Regulations, of the security either at the time the person is granted the right
to purchase securities under the plan or agreement or at the time the purchase
is consummated)] and the total number of securities called for under any bonus
or similar plan or agreement exceeded 30% of the Company's then outstanding
securities, calculated on an as-converted to common stock basis, shall be void.

4.    ELIGIBILITY.

      Options shall be granted only to Non-Employee Directors of the Company.

5.    NON-DISCRETIONARY GRANTS AND COMPENSATION.

      (a) Upon the effectiveness of the registration statement for the initial
public offering (the "IPO") of the Company, each person who is then a
Non-Employee Director, and after the IPO, upon the election to the Board of
Directors of a new member who is a Non-Employee Director, automatically shall be
granted options to purchase Five Thousand (5,000) shares of common stock of the
Company (an "Initial Grant") on the terms and conditions set forth herein;
provided, however, that (unless otherwise determined by a majority of
disinterested Directors) such Initial Grant shall only be granted to
Non-Employee Directors who have not previously been granted stock options or had
the opportunity to purchase restricted stock in the Company in connection with
their service as a Director of the Company.

                                       2.
<PAGE>

      (b) Each person who is a Non-Employee Director on any anniversary of the
IPO automatically shall, on such anniversary, be granted an option to purchase
Five Thousand (5,000) shares of common stock of the Company on the terms and
conditions set forth herein (an "Annual Grant").

6.    OPTION PROVISIONS.

      Each option shall be subject to the following terms and conditions:

      (a) The term of each option commences on the date it is granted and,
unless sooner terminated as set forth herein, expires on the date five (5) years
from the date of grant ("Expiration Date"). If the optionee's service as a
Non-Employee Director of the Company or an employee, member of the Board of
Directors or consultant to the Company or any Affiliate terminates for any
reason or for no reason, the option shall terminate on the earlier of the
Expiration Date or the date twelve (12) months following the date of termination
of all such service; provided, however, that if such termination of service is
due to the optionee's death, the option shall terminate on the earlier of the
Expiration Date or eighteen (18) months following the date of the optionee's
death.

      (b) The exercise price of each option shall be equal to one hundred
percent (100%) of the Fair Market Value of the stock (as such term is defined in
subsection 9(d)) subject to such option on the date such option is granted.

      (c) The optionee may elect to make payment of the exercise price under one
of the following alternatives:

            (i) Payment of the exercise price per share in cash at the time of
exercise;

            (ii) Provided that at the time of the exercise the Company's common
stock is publicly traded and quoted regularly in The Wall Street Journal,
payment by delivery of shares of common stock of the Company already owned by
the optionee, held for the period required to avoid a charge to the Company's
reported earnings, and owned free and clear of any liens, claims, encumbrances
or security interest, which common stock shall be valued at its Fair Market
Value on the date preceding the date of exercise; or

            (iii) Payment pursuant to a program developed under Regulation T as
promulgated by the Federal Reserve Board which results in the receipt of cash
(or check) by the Company either prior to the issuance of shares of the
Company's common stock or pursuant to the terms of irrevocable instructions
issued by the optionee prior to the issuance of shares of the Company's common
stock.

            (iv) Payment by a combination of the methods of payment specified in
subparagraph 6(c)(i) through 6(c)(iii) above.

      (d) An option shall not be transferable except by will or by the laws of
descent and distribution and, to the extent provided in the option agreement, to
such further extent as

                                       3.

permitted by Section 260.140.41(d) of Title 10 of the California Code of
Regulations at the time of the grant of the option, and shall be exercisable
during the lifetime of the optionee only by the optionee. If the option does not
provide for transferability, then the option shall not be transferable except by
will or by the laws of descent and distribution and shall be exercisable during
the lifetime of the optionee only by the optionee. Notwithstanding the
foregoing, the optionee may, by delivering written notice to the Company, in a
form satisfactory to the Company, designate a third party who, in the event of
the death of the optionee, shall thereafter be entitled to exercise the option.

      (e) The Initial Grant shall be fully vested at the time of grant.

      (f) The Annual Grant shall be fully vested at the time of grant.

      (g) The Company may require any optionee, or any person to whom an option
is transferred under subparagraph 6(d), as a condition of exercising any such
option: (i) to give written assurances satisfactory to the Company as to the
optionee's knowledge and experience in financial and business matters; and (ii)
to give written assurances satisfactory to the Company stating that such person
is acquiring the stock subject to the option for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
These requirements, and any assurances given pursuant to such requirements,
shall be inoperative if (i) the issuance of the shares upon the exercise of the
option has been registered under a then currently-effective registration
statement under the Securities Act of 1933, as amended (the "Securities Act"),
or (ii) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may require any optionee to provide
such other representations, written assurances or information that the Company
shall determine is necessary, desirable or appropriate to comply with applicable
securities laws as a condition of granting an option to the optionee or
permitting the optionee to exercise the option. The Company may, upon advice of
counsel to the Company, place legends on stock certificates issued under the
Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting
the transfer of the stock.

      (h) Notwithstanding anything to the contrary contained herein, an option
may not be exercised unless the shares issuable upon exercise of such option are
then registered under the Securities Act or, if such shares 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.

7.    COVENANTS OF THE COMPANY.

      (a) During the terms of the options granted under the Plan, the Company
shall keep available at all times the number of shares of stock required to
satisfy such options.

      (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the options granted under the
Plan; provided however, that this

                                       4.
<PAGE>

undertaking shall not require the Company to register under the Securities Act
either the Plan, any option granted under the Plan, or any stock issued or
issuable pursuant to any such option. If, after reasonable efforts, the Company
is unable to obtain from any such regulatory commission or agency the authority
which counsel for the Company deems necessary for the lawful issuance and sale
of stock under the Plan, the Company shall be relieved from any liability for
failure to issue and sell stock upon exercise of such options.

8.    USE OF PROCEEDS FROM STOCK.

      Proceeds from the sale of stock pursuant to options granted under the Plan
shall constitute general funds of the Company.

9.    MISCELLANEOUS.

      (a) Neither an optionee nor any person to whom an option is transferred
under subparagraph 6(d) shall be deemed to be the holder of, or to have any of
the rights of a holder with respect to, any shares subject to such option unless
and until such person has satisfied all requirements for exercise of the option
pursuant to its terms.

      (b) Nothing in the Plan or in any instrument executed pursuant thereto
shall confer upon any Non-Employee Director any right to continue in the service
of the Company or any Affiliate in any capacity or shall affect any right of the
Company, its Board or shareholders or any Affiliate, to remove any Non-Employee
Director pursuant to the Company's Bylaws and the provisions of Delaware general
corporation law.

      (c) In connection with each option made pursuant to the Plan, it shall be
a condition precedent to the Company's obligation to issue or transfer shares to
a Non-Employee Director, or to evidence the removal of any restrictions on
transfer, that such Non-Employee Director make arrangements satisfactory to the
Company to insure that the amount of any federal, state or local withholding tax
required to be withheld with respect to such sale or transfer, or such removal
or lapse, is made available to the Company for timely payment of such tax.

      (d) As used in this Plan, "Fair Market Value" means, as of any date, the
value of the common stock of the Company determined as follows:

            (i) If the common stock is listed on any established stock exchange
or a national market system, including without limitation the Nasdaq National
Market or The Nasdaq SmallCap, or is quoted on the OTC Bulletin Board, the Fair
Market Value of a share of common stock shall be the closing sales price for
such stock (or the closing bid, if no sales were reported) as quoted on such
system, exchange or board (or the exchange with the greatest volume of trading
in common stock) on the last market trading day prior to the day of
determination, as reported in The Wall Street Journal or such other source as
the Board deems reliable; or

            (ii) In the absence of an established market for the common stock,
the Fair Market Value shall be determined in good faith by the Board and to the
extent that the Company

                                       5.
<PAGE>

is subject to Section 260.140.50 of Title 10 of the California Code of
Regulations ("Section 260.140.50") at the time the option is granted, in a
manner consistent with Section 260.140.50.

      (e) To the extent required by Section 260.140.46 of Title 10 of the
California Code of Regulations, the Company shall deliver financial statements
to Participants at least annually. This Section 14 shall not apply to key
Employees whose duties in connection with the Company assure them access to
equivalent information.

10.   ADJUSTMENTS UPON CHANGES IN STOCK.

      (a) If any change is made in the stock subject to the Plan, or subject to
any option granted under the Plan (through merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan and outstanding options will
be appropriately adjusted in the class(es) and maximum number of shares subject
to the Plan and the class(es) and number of shares and price per share of stock
subject to outstanding options. The Board shall make such adjustments, and the
determination of the Board shall be final, binding and conclusive. (The
conversion of any convertible securities of the Company shall not be treated as
a "transaction not involving the receipt of consideration by the Company.")

      (b) In the event of: (1) a dissolution, liquidation, or sale of all or
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving corporation; or (3) a reverse merger in
which the Company is the surviving corporation but the shares of the Company's
common stock outstanding immediately preceding the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash or otherwise, then (i) any surviving or acquiring corporation shall assume
any options outstanding under the Plan or shall substitute similar options
(including an option to acquire the same consideration paid to the shareholders
in the transaction described in this subparagraph 10(b)) for those outstanding
under the Plan, or (ii) in the event any surviving corporation or acquiring
corporation refuses to assume such options or to substitute similar options for
those outstanding under the Plan, then such options shall be terminated if not
exercised prior to such event.

      (c) In the event of the acquisition by any person, entity or group within
the meaning of Section 13(d) or 14(d) of the Exchange Act, or any comparable
successor provisions (excluding any employee benefit plan, or related trust,
sponsored or maintained by the Company or any Affiliate of the Company) of the
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
Exchange Act, or comparable successor rule) of securities of the Company
representing at least fifty percent (50%) of the combined voting power entitled
to vote in the election of directors, then, with respect to options held by
persons whose continuous service has not terminated, the vesting of such options
(and, if applicable, the time during which such options may be exercised) shall
be accelerated immediately upon the happening of such event.

                                       6.

11.   AMENDMENT OF THE PLAN.

      (a) The Board at any time, and from time to time, may amend the Plan
and/or some or all outstanding options granted under the Plan. However, except
as provided in paragraph 10 relating to adjustments upon changes in stock, no
amendment shall be effective unless approved by the shareholders of the Company
to the extent shareholder approval is necessary for the Plan to satisfy the
requirements of Rule 16b-3 under the Exchange Act or any Nasdaq or securities
exchange listing requirements.

      (b) Rights and obligations under any option granted before any amendment
of the Plan shall not be impaired by such amendment unless (i) the Company
requests the consent of the person to whom the option was granted and (ii) such
person consents in writing.

12.   TERMINATION OR SUSPENSION OF THE PLAN.

      (a) The Board may suspend or terminate the Plan at any time. Unless sooner
terminated, the Plan shall terminate ten (10) years after the date adopted by
the Board. No options may be granted under the Plan while the Plan is suspended
or after it is terminated.

      (b) Suspension or termination of the Plan shall not impair rights and
obligations under any option granted while the Plan is in effect, except with
the consent of the person to whom the option was granted.

13.   EFFECTIVE DATE OF PLAN; CONDITIONS OF EXERCISE.

      (a) The Plan shall become effective on the same day that the Company's
initial public offering of shares of common stock becomes effective, subject to
the condition subsequent that the shareholders of the Company approve the Plan.

      (b) No option granted under the Plan shall be exercised or exercisable
unless and until the condition of subparagraph 13(a) above has been met.

                                       7.
