the Plan, the maximum aggregate number of Shares which may be optioned and sold
under the Plan is 250,000 Shares of Common Stock (the "Pool"). The Shares may be
authorized, but unissued, or reacquired Common Stock.

        If an Option expires or becomes unexercisable without having been
exercised in full, the unpurchased Shares which were subject thereto shall
become available for future grant or sale under the Plan (unless the Plan has
terminated). Shares that have actually been issued under the Plan shall not be
returned to the Plan and shall not become available for future distribution
under the Plan.

        4. Administration and Grants of Options under the Plan.

           (a) Procedure for Grants. All grants of Options to Outside Directors
under this Plan shall be automatic and nondiscretionary and shall be made
strictly in accordance with the following provisions:

               (i) No person shall have any discretion to select which Outside
Directors shall be granted Options or to determine the number of Shares to be
covered by Options granted to Outside Directors.

               (ii) Each Outside Director shall be automatically granted an
Option to purchase 50,000 Shares (the "First Option") on the date on which the
later of the following events occurs: (A) the effective date of this Plan, as
determined in accordance with Section 6 hereof, or (B) the date on which such
person first becomes an Outside Director, whether through election by the
stockholders of the Company or appointment by the Board to fill a vacancy;
provided, however, that an Inside Director who ceases to be an Inside Director
but who remains a Director shall not receive a First Option.

               (iii) Each Outside Director shall be automatically granted an
Option to purchase 5,000 Shares (a "Subsequent Option") on the date of the
annual meeting of stockholders of each year provided he or she is then an
Outside Director and if as of such date, he or she shall have served on the
Board for at least the preceding six (6) months.

               (iv) Notwithstanding the provisions of subsections (ii) and (iii)
hereof, any exercise of an Option granted before the Company has obtained
shareholder approval of the Plan in accordance with Section 16 hereof shall be
conditioned upon obtaining such shareholder approval of the Plan in accordance
with Section 16 hereof.

               (v) The terms of a First Option granted hereunder shall be as
follows:

                   (A) the term of the First Option shall be ten (10) years.

                   (B) the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

                                       2
<PAGE>   3

                   (C) the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the First Option. In the event
that the date of grant of the First Option is not a trading day, the exercise
price per Share shall be the Fair Market Value on the next trading day
immediately following the date of grant of the First Option.

                   (D) subject to Section 10 hereof, the First Option shall
become exercisable as to 1/4th of the Shares subject to the First Option on the
day before the annual meeting of stockholders of each year or, if no such
meeting is held, on each anniversary of the date of grant, provided that the
Optionee continues to serve as a Director on such dates.

               (vi) The terms of a Subsequent Option granted hereunder shall be
as follows:

                    (A) the term of the Subsequent Option shall be ten (10)
years.

                    (B) the Subsequent Option shall be exercisable only while
the Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

                    (C) the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the Subsequent Option. In the
event that the date of grant of the Subsequent Option is not a trading day, the
exercise price per Share shall be the Fair Market Value on the next trading day
immediately following the date of grant of the Subsequent Option.

                    (D) subject to Section 10 hereof, the Subsequent Option
shall become exercisable as to 1/4th of the Shares subject to the Subsequent
Option on the day before the annual meeting of stockholders of each year or, if
no such meeting is held, on each anniversary of the date of grant, provided that
the Optionee continues to serve as a Director on such dates.

               (vii) In the event that any Option granted under the Plan would
cause the number of Shares subject to outstanding Options plus the number of
Shares previously purchased under Options to exceed the Pool, then the remaining
Shares available for Option grant shall be granted under Options to the Outside
Directors on a pro rata basis. No further grants shall be made until such time,
if any, as additional Shares become available for grant under the Plan through
action of the Board or the stockholders to increase the number of Shares which
may be issued under the Plan or through cancellation or expiration of Options
previously granted hereunder.

        5. Eligibility. Options may be granted only to Outside Directors. All
Options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof.

        The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate the Director's relationship with the Company at any time.

        6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board or its approval by the stockholders of the
Company as described in Section 16 of the Plan. It shall continue in effect for
a term of ten (10) years unless sooner terminated under Section 11 of the Plan.

        7. Form of Consideration. The consideration to be paid for the Shares to
be issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) in the case of
Shares acquired upon exercise of an Option, have been owned by the Optionee for
more than six (6) months on the date of surrender, and (y) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which said Option shall be exercised, (iv) consideration received
by the Company under a cashless exercise program implemented by the Company in
connection with the Plan, or (v) any combination of the foregoing methods of
payment.

                                       3

        8. Exercise of Option.

           (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable at such times as are set forth in Section
4 hereof; provided, however, that no Options shall be exercisable until
shareholder approval of the Plan in accordance with Section 16 hereof has been
obtained.

        An Option may not be exercised for a fraction of a Share.

        An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may consist of any consideration and method of payment
allowable under Section 7 of the Plan. Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, 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.
A share certificate for the number of Shares so acquired shall be issued to the
Optionee as soon as practicable after exercise of the Option. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date the stock certificate is issued, except as provided in Section 10 of
the Plan.

        Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

           (b) Termination of Continuous Status as a Director. Subject to
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or total and permanent disability (as
defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or her
Option, but only within three (3) months following the date of such termination,
and only to the extent that the Optionee was entitled to exercise it on the date
of such termination (but in no event later than the expiration of its ten (10)
year term). To the extent that the Optionee was not entitled to exercise an
Option on the date of such termination, and to the extent that the Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

           (c) Disability of Optionee. In the event Optionee's status as a
Director terminates as a result of total and permanent disability (as defined in
Section 22(e)(3) of the Code), the Optionee may exercise his or her Option, but
only within twelve (12) months following the date of such termination, and only
to the extent that the Optionee was entitled to exercise it on the date of such
termination (but in no event later than the expiration of its ten (10) year
term). To the extent that the Optionee was not entitled to exercise an Option on
the date of termination, or if he or she does not exercise such Option (to the
extent otherwise so entitled) within the time specified herein, the Option shall
terminate.

           (d) Death of Optionee. In the event of an Optionee's death, the
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

        9. Non-Transferability of Options. Unless otherwise determined by the
Board, the Option may not be sold, pledged, assigned, hypothecated, transferred,
or disposed of in any manner other than by will or by the laws of descent or
distribution and may be exercised, during the lifetime of the Optionee, only by
the Optionee.

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

            (a) Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the number of Shares covered by each outstanding
Option, the number of Shares which have been authorized for issuance under the
Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option, as well as
the price per Share covered by each such outstanding Option, and the number of
Shares

                                       4
<PAGE>   5

issuable pursuant to the automatic grant provisions of Section 4 hereof shall be
proportionately adjusted for any increase or decrease in the number of issued
Shares 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 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." 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
subject to an Option.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall 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, outstanding Options may be assumed or equivalent options may be
substituted by the successor corporation or a Parent or Subsidiary thereof (the
"Successor Corporation"). If an Option is assumed or substituted for, the Option
or equivalent option shall continue to be exercisable as provided in Section 4
hereof for so long as the Optionee serves as a Director or a director of the
Successor Corporation. Following such assumption or substitution, if the
Optionee's status as a Director or director of the Successor Corporation, as
applicable, is terminated other than upon a voluntary resignation by the
Optionee, the Option or option shall become fully exercisable, including as to
Shares for which it would not otherwise be exercisable. Thereafter, the Option
or option shall remain exercisable in accordance with Sections 8(b) through (d)
above.

        If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable, including as to Shares for which it would not otherwise be
exercisable. In such event the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

        For the purposes of this Section 10(c), an Option shall be considered
assumed if, following the merger or sale of assets, the Option 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).
If such consideration received in the 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, 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.

        11. Amendment and Termination of the Plan.

            (a) Amendment and Termination. The Board may at any time amend,
alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with any applicable
law, regulation or stock exchange rule, the Company shall obtain shareholder
approval of any Plan amendment in such a manner and to such a degree as
required.

            (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

        12. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date determined in accordance with Section 4 hereof.

        13. Conditions Upon Issuance of Shares. 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 pursuant thereto shall comply with all

                                       5
<PAGE>   6

relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of any stock exchange
upon which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

        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 by any of the
aforementioned relevant provisions of law.

        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.

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

        15. Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve.

        16. Shareholder Approval. Continuance of the Plan shall be subject to
approval by the stockholders of the Company at or prior to the first annual
meeting of stockholders held subsequent to the granting of an Option hereunder.
Such shareholder approval shall be obtained in the degree and manner required
under applicable state and federal law and any stock exchange rules.

                              INGENUUS CORPORATION

                         1997 DIRECTOR STOCK OPTION PLAN

                            DIRECTOR OPTION AGREEMENT

        Ingenuus Corporation, a Delaware corporation (the "Company"), has
granted to ____________ (the "Optionee"), an option to purchase a total of
[________ (_____)] shares of the Company's Common Stock (the "Optioned Stock"),
at the price determined as provided herein, and in all respects subject to the
terms, definitions and provisions of the Company's 1997 Director Stock Option
Plan (the "Plan") adopted by the Company which is incorporated herein by
reference. The terms defined in the Plan shall have the same defined meanings
herein.

        1. Nature of the Option. This Option is a nonstatutory option and is not
intended to qualify for any special tax benefits to the Optionee.

        2. Exercise Price. The exercise price is $________ for each share of
Common Stock.

        3. Exercise of Option. This Option shall be exercisable during its term
in accordance with the provisions of Section 8 of the Plan as follows:

           (a) Right to Exercise.

               (i) This Option shall become exercisable in installments
cumulatively with respect to 1/4th of the Shares subject to the Option on the
day before the annual meeting of stockholders of each year or, if no such
meeting is held, on each anniversary of the date of grant, provided that the
Optionee continues to serve as a Director on such dates; provided, however, that
in no event shall any Option be exercisable prior to the date the stockholders
of the Company approve the Plan.

               (ii) This Option may not be exercised for a fraction of a share.

               (iii) In the event of Optionee's death, disability or other
termination of service as a Director, the exercisability of the Option is
governed by Section 8 of the Plan.

           (b) Method of Exercise. This Option shall be exercisable by written
notice which shall state the election to exercise the Option and the number of
Shares in respect of which the Option is being exercised. Such written notice,
in the form attached hereto as Exhibit A, shall be signed by the Optionee and
shall be delivered in person or by certified mail to the Secretary of the
Company. The written notice shall be accompanied by payment of the exercise
price.

        4. Method of Payment. Payment of the exercise price shall be by any of
the following, or a combination thereof, at the election of the Optionee:

            (a) cash;

            (b) check;

            (c) surrender of other shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (y) have a Fair Market Value
on the date of surrender equal to the aggregate exercise price of the Shares as
to which said Option shall be exercised; or

            (d) delivery of a properly executed exercise notice together with
such other documentation as the Company and the broker, if applicable, shall
require to effect an exercise of the Option and delivery to the Company of the
sale or loan proceeds required to pay the exercise price.

<PAGE>   8

        5. Restrictions on Exercise. This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulations, or if such issuance
would not comply with the requirements of any stock exchange upon which the
Shares may then be listed. As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

        6. 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 the Optionee. The terms
of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

        7. Term of Option. This Option may not be exercised more than ten (10)
years from the date of grant of this Option, and may be exercised during such
period only in accordance with the Plan and the terms of this Option.

        8. Taxation Upon Exercise of Option. Optionee understands that, upon
exercise of this Option, he or she will recognize income for tax purposes in an
amount equal to the excess of the then Fair Market Value of the Shares purchased
over the exercise price paid for such Shares. Since the Optionee is subject to
Section 16(b) of the Securities Exchange Act of 1934, as amended, under certain
limited circumstances the measurement and timing of such income (and the
commencement of any capital gain holding period) may be deferred, and the
Optionee is advised to contact a tax advisor concerning the application of
Section 83 in general and the availability of a Section 83(b) election in
particular in connection with the exercise of the Option. Upon a resale of such
Shares by the Optionee, any difference between the sale price and the Fair
Market Value of the Shares on the date of exercise of the Option, to the extent
not included in income as described above, will be treated as capital gain or
loss.

Ingenuus Corporation
830 East Arques Avenue
Sunnyvale, CA 94086

Attention: Corporate Secretary

        1. Exercise of Option. The undersigned ("Optionee") hereby elects to
exercise Optionee's option to purchase shares of the Common Stock (the "Shares")
of Ingenuus Corporation (the "Company") under and pursuant to the Company's 1997
Director Stock Option Plan and the Director Option Agreement dated (the
"Agreement").

        2. Representations of Optionee. Optionee acknowledges that Optionee has
received, read and understood the Agreement.

        3. Federal Restrictions on Transfer. Optionee understands that the
Shares must be held indefinitely unless they are registered under the Securities
Act of 1933, as amended (the "1933 Act"), or unless an exemption from such
registration is available, and that the certificate(s) representing the Shares
may bear a legend to that effect. Optionee understands that the Company is under
no obligation to register the Shares and that an exemption may not be available
or may not permit Optionee to transfer Shares in the amounts or at the times
proposed by Optionee.

        4. Tax Consequences. Optionee understands that Optionee may suffer
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares. Optionee represents that Optionee has consulted with any tax
consultant(s) Optionee deems advisable in connection with the purchase or
disposition of the Shares and that Optionee is not relying on the Company for
any tax advice.

        5. Delivery of Payment. Optionee herewith delivers to the Company the
aggregate purchase price for the Shares that Optionee has elected to purchase
and has made provision for the payment of any federal or state withholding taxes
required to be paid or withheld by the Company.

        6. Entire Agreement. The Agreement is incorporated herein by reference.
This Exercise Notice and the Agreement constitute the entire agreement of the
parties and supersede in their entirety all prior undertakings and agreements of
the Company and Optionee with respect to the subject matter hereof. This
Exercise Notice and the Agreement are governed by Delaware law except for that
body of law pertaining to conflict of laws.

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 under the Plan (unless the Plan has terminated); provided,
however, that Shares that have actually been issued under the Plan shall not be

                                      -3-
<PAGE>   4

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

                    (v) to approve forms of agreement for use under the Plan;

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

                    (vii) to reduce the exercise price of any 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;

                    (viii) to institute an Option Exchange Program;

                    (ix) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

                    (x) to prescribe, amend and rescind Rules and regulations
relating to the Plan, including Rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

                    (xi) to modify or amend each Option (subject to Section
14(b) of the Plan), including the discretionary authority to extend the
post-termination exercisability period of Options longer than is otherwise
provided for in the Plan;

                    (xii) to determine the terms and restrictions applicable to
Options;

                    (xiii) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an 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. All elections by an 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;

                    (xiv) 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;

                    (xv) to make all other determinations deemed necessary or
advisable for administering the Plan.

<PAGE>   5

                (c) Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

        5.      Eligibility. Options may be granted to Service Provider;
provided, however, that notwithstanding anything to the contrary contained in
the Plan, Options may not be granted to Officers and Directors.

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

        7.      Term of Plan. The Plan shall become effective upon its adoption
by the Board. It shall continue in effect for a term of ten (10) years unless
terminated earlier under Section 14 of the Plan.

        8.      Term of Option. The term of each Option shall be stated in the
Option Agreement.

        9.      Option Exercise Price and Consideration.

                (a) Exercise Price. The per share exercise price for the Shares
to be issued pursuant to exercise of an Option shall be determined by the
Administrator.

                (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

                (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. Such consideration may consist entirely of:

                    (i) cash

                    (ii) check

                    (iii) promissory note;

                    (iv) other Shares which (A) in the case of Shares acquired
upon exercise of an option, have been owned by the Optionee for more than six
(6) months on the date of surrender, and (B) have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

                    (v) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

                                      -5-
<PAGE>   6

                    (vi) a reduction in the amount of any Company liability to
the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                    (vii) any combination of the foregoing methods of payment;
or

                    (viii) such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws; or

                    (ix) any combination of the foregoing methods of payment.

        10.     Exercise of Option.

                (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence.

        An Option may not be exercised for a fraction of a Share. An Option
shall be deemed exercised when the Company receives: (i) written or electronic
notice of exercise (in accordance with the Option Agreement) from the person
entitled to exercise the Option, and (ii) full payment for the Shares with
respect to which the Option is exercised. Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan. Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her 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 Section 12 of the Plan.

        Exercising an Option in any manner shall decrease the number of Shares
thereafter available, both for purposes of the Plan and for sale under the
Option, by the number of Shares as to which the Option is exercised.

                (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option Agreement, and only 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 Option Agreement).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for three (3) months following the Optionee's termination.
If, on the date of termination, the Optionee is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or
her Option within the time specified

                                      -6-
<PAGE>   7

by the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

                (c) Disability of Optionee. If an Optionee ceases to be a
Service Provider as a result of the Optionee's Disability, the Optionee may
exercise his or her Option within such period of time as is specified in the
Option Agreement 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 Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

                (d) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the 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. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the 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 Plan.

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

        11.     Non-Transferability of Options. Unless determined otherwise by
the Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

        12.     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
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the

                                      -7-
<PAGE>   8

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 Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her 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 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 where the Company is not the surviving
entity, or the sale of substantially all of the assets of the Company, each
outstanding Option shall be fully vested and exercisable, including Shares which
would not otherwise be vested or exercisable. If an Option becomes fully vested
and exercisable, the Administrator shall notify the Option 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, 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 Administrator 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 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.

        13.     Date of Grant. The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting

reasonable time after the date of such grant.

        14.     Amendment and Termination of the Plan.

                (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

                (b) Effect of Amendment or Termination. No amendment,
alteration, suspension or termination of the Plan shall impair the rights of any
Optionee, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee and
the Company. Termination of the Plan shall not affect the Administrator's
ability to exercise the powers granted to it hereunder with respect to Options
granted under the Plan prior to the date of such termination.

        15.     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.

                (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.

        16.     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.

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

        II.     AGREEMENT

                (a) Grant of Option. The Plan Administrator of the Company
hereby grants to the Optionee named in the Notice of Grant attached as Part I of
this Agreement (the "Optionee") an option (the "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 the Plan, which is incorporated herein by reference. In the
event of a conflict between the terms and conditions of the Plan and the terms
and conditions of this Option Agreement, the terms and conditions of the Plan
shall prevail.

                (b) Exercise of Option.

                    (i) 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 the Plan and this Option Agreement.

                    (ii) 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 the Plan. The Exercise Notice shall be
completed by the Optionee and delivered to Secretary of the Company. The
Exercise Notice shall be accompanied by payment of the aggregate Exercise Price
as to all Exercised Shares. This Option shall be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.

        No Shares shall be issued pursuant to the exercise of this Option unless
such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

                (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
the Optionee:

                    (i) cash;

                    (ii) check; or

                    (iii) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan.

<PAGE>   12

                (d) 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 the
Optionee. The terms of the Plan and this Option Agreement shall be binding upon
the executors, administrators, heirs, successors and assigns of the Optionee.

                (e) 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 Plan and the terms of this Option Agreement.

                (f) 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. THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

                    (i) Exercising the Option. The Optionee may incur regular
federal income tax liability upon exercise of an NSO. The 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 the
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.

                    (ii) Disposition of Shares. If the 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.

                (g) Entire Agreement; Governing Law. The Plan is incorporated
herein by reference. The Plan and this Option Agreement constitute 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 the 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.

                (h) 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

                                      -3-
<PAGE>   13

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.

        By your signature and the signature of the Company's representative
below, you and the Company agree that this Option is granted under and governed
by the terms and conditions of the Plan and this Option Agreement. Optionee has
reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
Agreement and fully understands all provisions of the Plan and Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions relating to the Plan
and Option Agreement. Optionee further agrees to notify the Company upon any
change in the residence address indicated below.
