Item 9. UNDERTAKINGS

        (a) The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

               (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

               (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

        (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934, as amended, that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

        (c) Insofar as indemnification for liabilities arising under the Act may
be permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such


                                      -2-
<PAGE>   4
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933, as amended, and will be
governed by the final adjudication of such issue.

the Registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-8 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Sunnyvale, State of California, on this 31st day

            -     to promote the success of the Company's business.

      Options granted under the Plan may be Incentive Stock Options or
Nonstatutory Stock Options, as determined by the Administrator at the time of
grant. Stock Purchase Rights may also be granted under the Plan.

      All share numbers in this Plan reflect the 1-for-10 reverse split

            (dd)  "Service Provider" means an Employee, Director or Consultant.

            (ee)  "Share" means a share of the Common Stock, as adjusted in
accordance with Section 14 of the Plan.


                                      -3-
<PAGE>   4
            (ff)  "Stock Purchase Right" means the right to purchase Common
Stock pursuant to Section 11 of the Plan, as evidenced by a Notice of Grant.

            (gg)  "Subsidiary" means a "subsidiary corporation", whether now or
hereafter existing, as defined in Section 424(f) of the Code.

      3.    Stock Subject to the Plan. Subject to the provisions of Section 14
of the Plan, the maximum aggregate number of Shares which may be optioned and
sold under the Plan is 1,200,000 Shares, plus an annual increase to be added on
the first day of the Company's fiscal year, beginning in April 1, 2000, equal to
the lesser of (i) 500,000 Shares or (ii) 5% of the outstanding Shares on the
last day of the immediately preceding fiscal year; provided, however, that until
such time as the Company's Common Stock is traded on any established national
stock exchange or national market system (including without limitation the
Nasdaq National Market or the Nasdaq SmallCap Market of the Nasdaq Stock
Market), at no time shall the total number of shares issuable upon exercise of
all outstanding options to purchase Common Stock of the Company, when aggregated
with the total number of shares provided for under any and all stock bonus or
similar plans of the Company, exceed 40% of the outstanding shares of the
Company as calculated in accordance with the conditions and exclusions of
Section 260.140.45 of Title 10 of the California Code of Regulations, based on
the shares of the Company which are outstanding at the time the calculation is
made. The Shares may be authorized, but unissued, or reacquired Common Stock.

            If an Option or Stock Purchase Right 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); provided, however, that Shares that
have actually been issued under the Plan, whether upon exercise of an Option or
Right, shall not be returned to the Plan and shall not become available for
future distribution under the Plan, except that if Shares of Restricted Stock
are repurchased by the Company at their original purchase price, such Shares
shall become available for future grant under the Plan.

      4.    Administration of the Plan.

            (a)   Procedure.

                  (i)   Multiple Administrative Bodies. The Plan may be
administered by different Committees with respect to different groups of Service
Providers.

                  (ii)  Section 162(m). To the extent that the Administrator
determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

                  (iii) Rule 16b-3. To the extent desirable to qualify
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3.


                                      -4-
<PAGE>   5
                  (iv)  Other Administration. Other than as provided above, the
Plan shall be administered by (A) the Board or (B) a Committee, which committee
shall be constituted to satisfy Applicable Laws.

            (b)   Powers of the Administrator. Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

                  (i)   to determine the Fair Market Value;

                  (ii)  to select the Service Providers to whom Options and
Stock Purchase Rights may be granted hereunder;

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

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

                  (v)   to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any Option or Stock Purchase Right granted
hereunder. Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Options or Stock Purchase Rights 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 or Stock Purchase Right or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

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

                  (vii) 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 treatment under foreign
laws;

                  (viii) to modify or amend each Option or Stock Purchase Right
(subject to Section 16(c) 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;

                  (ix)  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 or Stock Purchase Right that number of Shares
having a Fair Market Value equal to (or lesser than) the minimum 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;


                                      -5-
<PAGE>   6
                  (x)   to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

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

            (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 or Stock Purchase Rights.

      5.    Eligibility. Nonstatutory Stock Options and Stock Purchase Rights
may be granted to Service Providers. Incentive Stock Options may be granted only
to Employees.

      6.    Limitations.

            (a)   Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

            (b)   Neither the Plan nor any Option or Stock Purchase Right 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.

            (c)   The following limitations shall apply to grants of Options:

                  (i)   No Service Provider shall be granted, in any fiscal year
of the Company, Options to purchase more than 500,000 Shares.

                  (ii)  In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 100,000 Shares
which shall not count against the limit set forth in subsection (i) above.

                  (iii) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 14.

      7.    Term of Plan. Subject to Section 20 of the 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 16 of the Plan.


                                      -6-
<PAGE>   7
      8.    Term of Option. The term of each Option shall be stated in the
Option Agreement. In the case of an Incentive Stock Option, the term shall be
ten (10) years from the date of grant or such shorter term as may be provided in
the Option Agreement. Moreover, in the case of an Incentive Stock Option granted
to an Optionee who, at the time the Incentive Stock Option is granted, owns
stock representing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
term of the Incentive Stock Option shall be five (5) years from the date of
grant or such shorter term as may be provided 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 no less than 100% of Fair
Market Value, as determined by the Administrator. Notwithstanding the foregoing,
Options may be granted with a per Share exercise price of less than 100% of the
Fair Market Value per Share on the date of grant pursuant to a merger or other
corporate transaction.

            (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 that 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. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. 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
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;

                  (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


                                      -7-
<PAGE>   8
                  (viii) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

      10.   Exercise of Option.

            (a)   Procedure for Exercise; Rights as a Stockholder. 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 in writing
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 stockholder 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 14 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. Subject to
Section 14, 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 for
a period of at least thirty (30) days following Optionee's termination of
service or within such longer period of time as is specified in the Option
Agreement (but in no event later than the expiration date of the term of such
Option as set forth in the Option Agreement) to the extent that Optionee was
entitled to exercise it at the date of such 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 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, but only
within twelve (12) months from the date of such termination (and in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise his or her Option the extent the Option is vested on
the date of termination. If, on the date of termination, the Optionee is not
vested as to his or her entire


                                      -8-
<PAGE>   9
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 at any time within eighteen (18) months
following the date of death (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
designated beneficiary, provided such beneficiary has been designated prior to
Optionee's death in a form acceptable by the Administrator. If no such
beneficiary has been designated by the Optionee, then each such 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. The Option shall be exercisable following
Optionee's death only to the extent the Option is vested on the date of death.
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. 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.   Stock Purchase Rights.

            (a)   Rights to Purchase. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept such offer. The offer shall be
accepted by execution of a Restricted Stock Purchase Agreement in the form
determined by the Administrator.

            (b)   Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate or under such
conditions as shall be determined by the Administrator and set forth in the
Restricted Stock Purchase Agreement.

            (c)   Other Provisions. The Restricted Stock Purchase Agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion.


                                      -9-
<PAGE>   10
            (d)   Rights as a Stockholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
stockholder, and shall be a stockholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 14
of the Plan.

      12.   Transferability of Options and Stock Purchase Rights. Unless
determined otherwise by the Administrator, an Option or Stock Purchase Right 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 or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

      13.   Formula Option Grants to Outside Directors. Outside Directors shall
be automatically granted Options each year in accordance with the following
provisions:

            (a)   All Options granted pursuant to this Section shall be
Nonstatutory Stock Options and, except as otherwise provided herein, shall be
subject to the other terms and conditions of the Plan.

            (b)   Each person who is serving as an Outside Director on the date
this Option Plan is approved by the Company's stockholders shall automatically
be granted an Option to purchase 5,000 Shares.

            (c)   Each person who first becomes an Outside Director on or after
September 1, 1999, whether through election by the stockholders of the Company
or appointment by the Board, shall be automatically granted an Option to
purchase 5,000 Shares (the "First Option") on the date he or she first becomes
an Outside Director; provided, however, that an Inside Director who ceases to be
an Inside Director but who remains a Director shall not receive a First Option.

            (d)   Each Outside Director shall be automatically granted an Option
to purchase 2,000 Shares (a "Subsequent Option") on March 31st of each calendar
year, beginning with March 31, 2000, provided such individual has been an
Outsider Director for at least three (3) months on the date of each such grant.

            (e)   Notwithstanding the provisions of subsections (b) and (c)
hereof, any exercise of an Option granted before the Company has obtained
stockholder approval of the Plan in accordance with Section 20 hereof shall be
conditioned upon obtaining such stockholder approval of the Plan in accordance
with Section 20 hereof.

            (f)   The terms of each Option granted pursuant to this Section
shall be as follows:

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


                                      -10-
<PAGE>   11
                  (ii)  the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the Option.

                  (iii) the Option shall be fully vested and exercisable as to
100% of the Shares subject to the Option on its date of grant.

      14.   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 of Common Stock covered by
each outstanding Option and Stock Purchase Right, the number of shares of Common
Stock covered by First Options and Subsequent Options to be granted under the
Plan, the number of shares of Common Stock which have been authorized for
issuance under the Plan but as to which no Options or Stock Purchase Rights have
yet been granted or which have been returned to the Plan upon cancellation or
expiration of an Option or Stock Purchase Right and the number of shares of
Common Stock which may be added to the Plan each fiscal year (pursuant to
Section 3), as well as the price per share of Common Stock covered by each such
outstanding Option or Stock Purchase Right, shall be proportionately adjusted
for any increase or decrease in the number of issued shares of Common Stock
resulting from a stock split, reverse stock split, stock dividend, combination
or reclassification of the Common Stock, or any other increase or decrease in
the number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option or Stock
Purchase Right.

            (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 or Stock Purchase Right 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 or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

            (c)   Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the Option or
Stock Purchase Right, the


                                      -11-
<PAGE>   12
            Optionee shall fully vest in and have the right to exercise the
Option or Stock Purchase Right as to all of the Optioned Stock, including Shares
as to which it would not otherwise be vested or exercisable, provided, however,
that this sentence shall have no effect unless the Company's common stock is
traded on any established national stock exchange or national market system
(including without limitation the Nasdaq National Market or the Nasdaq SmallCap
Market of the Nasdaq Stock Market). If an Option or Stock Purchase Right becomes
fully vested and exercisable in lieu of assumption or substitution in the event
of a merger or sale of assets, the Administrator shall notify the Optionee in
writing or electronically that the Option or Stock Purchase Right shall be fully
vested and exercisable for a period of fifteen (15) days from the date of such
notice, and the Option or Stock Purchase Right shall terminate upon the
expiration of such period. For the purposes of this paragraph, the Option or
Stock Purchase Right shall be considered assumed if, following the merger or
sale of assets, the option or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option or Stock Purchase Right
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 or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the successor corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

      15.   Date of Grant. The date of grant of an Option or Stock Purchase
Right shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator. Notice of the determination shall be
provided to each Optionee within a reasonable time after the date of such grant.

      16.   Amendment and Termination of the Plan.

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

            (b)   Stockholder Approval. The Company shall obtain stockholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

            (c)   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.


                                      -12-
<PAGE>   13
      17.   Conditions Upon Issuance of Shares.

            (a)   Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock Purchase Right 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 or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right 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.

      18.   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.

      19.   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.

      20.   Stockholder Approval. The Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months after the date the Plan is
adopted. Such stockholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

      21.   Provisions Contingent Upon Lack of Exchange Listing. Notwithstanding
anything to the contrary contained elsewhere herein, so long as the Company's
common stock is not traded on a established national stock exchange or national
market system (including without limitation the Nasdaq National Market or the
Nasdaq SmallCap Market of the Nasdaq Stock Market), the additional provisions
contained on Schedule A hereto shall apply with full force and effect as
operative provisions of this Plan.

                                   SCHEDULE A

               PROVISIONS CONTINGENT UPON LACK OF EXCHANGE LISTING

TO REPLACE EXISTING SECTIONS 8 THROUGH 12:

      8.    Term of Option. The term of each Option shall be stated in the
Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof. In the case of an Incentive Stock
Option granted to an optionee who at the time of the grant owns stock
representing more than 10% of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, however, the term of the Option shall be
five (5) years from the date of the grant or such shorter term as may be
provided in the Option Agreement.

      9.    Option Exercise Price and Consideration.

            (a)   The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

                  (i)   In the case of an Incentive Stock Option

                        (A)   granted to an Employee who, at the time of grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the exercise price shall be no less than 110% of the Fair Market Value per Share
on the date of grant.

                        (B)   granted to any other Employee, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                  (ii)  In the case of a Nonstatutory Stock Option

                        (A)   granted to a Service Provider who, at the time of
grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the exercise price shall be no less than 110% of the Fair Market Value per Share
on the date of grant.

                        (B)   granted to any other Service Provider, the per
Share exercise price shall be no less than 85% of the Fair Market Value per
Share on the date of grant.

                  (iii) Notwithstanding the foregoing, Options may be granted
with a per Share exercise price other than as required above pursuant to a
merger or other corporate transaction.


                                      -14-
<PAGE>   15
            (b)   The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) 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 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 such Option shall be exercised, (5) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with
the Plan, or (6) any combination of the foregoing methods of payment. In making
its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

      10.   Exercise of Option.

            (c)   Procedure for Exercise; Rights as a Stockholder. Any Option
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement. Except in the case of Options granted to Officers,
Directors and Consultants, Options shall become exercisable at a rate of no less
than 20% per year over five (5) years from the date the Options are granted.
Unless the Administrator provides otherwise, vesting of Options granted
hereunder to Officers and Directors 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 stockholder shall exist with respect to the
Shares, 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 14 of
the Plan.

      Exercise of an Option in any manner shall result in a decrease in 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.

            (d)   Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, such Optionee may exercise his or her
Option within such period of time as is specified in the Option Agreement (of at
least thirty (30) days) 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 the Option
as set


                                      -15-
<PAGE>   16
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 by the
Administrator, the Option shall terminate, and the Shares covered by such Option
shall revert to the Plan.

            (e)   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
(of at least six (6) months) 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.

            (f)   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 (of at least six (6) months) to the extent that the
Option is vested on the date of death (but in no event later than the expiration
of the term of such Option as set forth in the Option Agreement) by the
Optionee's estate or by a person who acquires the right to exercise the Option
by bequest or inheritance. 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 the entire Option, the Shares covered by the unvested portion of the
Option shall immediately revert to the Plan. 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.

            (g)   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 and Stock Purchase Rights. The
Options and Stock Purchase Rights 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.

      12.   Stock Purchase Rights.

            (a)   Rights to Purchase. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that such person shall


                                      -16-
<PAGE>   17
be entitled to purchase, the price to be paid, and the time within which such
person must accept such offer. The terms of the offer shall comply in all
respects with Section 260.140.42 of Title 10 of the California Code of
Regulations. The offer shall be accepted by execution of a Restricted Stock
Purchase Agreement in the form determined by the Administrator.

            (b)   Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine. Except with respect to Shares purchased by
Officers, Directors and Consultants, the repurchase option shall in no case
lapse at a rate of less than 20% per year over five (5) years from the date of
purchase.

            (c)   Other Provisions. The Restricted Stock Purchase Agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion.

            (d)   Rights as a Stockholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
stockholder, and shall be a stockholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 14
of the Plan.

TO BE ADDED AS A NEW SECTION 22:

      22.   Information to Optionees and Purchasers. The Company shall provide
to each Optionee and to each individual who acquires Shares pursuant to the
Plan, not less frequently than annually during the period such Optionee or
purchaser has one or more Options or Stock Purchase Rights outstanding, and, in
the case of an individual who acquires Shares pursuant to the Plan, during the
period such individual owns such Shares, copies of annual financial statements.
The Company shall not be required to provide such statements to key employees
whose duties in connection with the Company assure their access to equivalent
information.

the following schedule:

      25% of the Shares subject to the Option shall vest twelve months after the

<PAGE>   2
      Termination Period:

      This Option shall be exercisable for three months after Optionee ceases to
be a Service Provider. Upon Optionee's death or Disability, this Option may be
exercised for twelve (12) months after Optionee ceases to be a Service Provider.
In no event shall this Option be exercised later than the Term/Expiration Date
as provided above.

      II.   AGREEMENT

            1.    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 set forth in the Notice of Grant, at the exercise price per Share set
forth in the Notice of Grant (the "Exercise Price"), and subject to the terms
and conditions of the Plan, which is incorporated herein by reference. Subject
to Section 16(c) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and this Option Agreement, the terms and conditions of
the Plan shall prevail.

      If designated in the Notice of Grant as an Incentive Stock Option ("ISO"),
this Option is intended to qualify as an Incentive Stock Option as defined in
Section 422 of the Code. However, if this Option is intended to be an ISO, to
the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option
shall be treated as a Nonstatutory Stock Option ("NSO").

            2.    Exercise of Option.

                  (a)   Right to Exercise. This Option shall be 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.

                  (b)   Method of Exercise. This Option shall be 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 with respect to which the Option is being exercised, and such other
representations and agreements as may be required by the Company. The Exercise
Notice shall be completed by the Optionee and delivered to 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 the
aggregate Exercise Price.

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

            3.    Optionee's Representations. The Optionee acknowledges that the
Shares issued upon exercise of the Option may be subject to the applicable rules
of the Commissioner of


                                      -2-
<PAGE>   3
Corporations attached hereto as Exhibit B. Optionee has read such rules and
agrees to be bound by such rules to the extent applicable.

            4.    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:

                  (a)   cash or check; or

                  (b)   consideration received by the Company under a formal
cashless exercise program adopted by the Company in connection with the Plan; or

                  (c)   surrender of other Shares which, (i) 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 (ii) have a Fair Market
Value on the date of surrender equal to the aggregate Exercise Price of the
Exercised Shares; or

                  (d)   with the Administrator's consent, delivery of Optionee's
promissory note (the "Note") in the form attached hereto as Exhibit C, in the
amount of the aggregate Exercise Price of the Exercised Shares together with the
execution and delivery by the Optionee of the Security Agreement attached hereto
as Exhibit D. The Note shall bear interest at the "applicable federal rate"
prescribed under the Code and its regulations at time of purchase, and shall be
secured by a pledge of the Shares purchased by the Note pursuant to the Security
Agreement.

            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
Law.

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

            7.    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.

            8.    Tax Consequences. Set forth below is a brief summary as of the
date of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. 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.

                  (a)   Exercise of NSO. The Optionee may incur regular federal
income tax liability upon the exercise of a 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


                                      -3-
<PAGE>   4
the Shares on the date of exercise over the aggregate Exercise Price. If
Optionee is an Employee or a former Employee, the Company will be required to
withhold from Optionee's compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

                  (b)   Exercise of ISO. If this Option qualifies as an ISO, the
Optionee will have no regular federal income tax liability upon the exercise of
the Option, although the excess, if any, of the Fair Market Value of the Shares
on the date of exercise over the aggregate Exercise Price will be treated as an
adjustment to the alternative minimum tax for federal tax purposes and may
subject the Optionee to the alternative minimum tax in the year of exercise. In
the event that the Optionee ceases to be an Employee but remains a Service
Provider, any ISO that remains unexercised shall cease to qualify as an ISO and
will be treated for tax purposes as a NSO on the date three (3) months and one
(1) day following such change of status.

                  (c)   Disposition of Shares. In the case of an NSO, if Shares
are held 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. In
the case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes. If Shares purchased under an ISO
are disposed of within one year after exercise or two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the aggregate Exercise Price and the lesser of (1) the Fair Market Value
of the Shares on the date of exercise, or (2) the aggregate sale price of the
Shares. Any additional gain will be taxed as capital gain, short-term or
long-term depending on the period that the ISO Shares were held.

                  (d)   Notice of Disqualifying Disposition of ISO Shares. If
the Option granted to Optionee herein is an ISO, and if Optionee sells or
otherwise disposes of any of the Shares acquired pursuant to the ISO on or
before the later of (1) the date two years after the Date of Grant, or (2) the
date one year after the date of exercise, the Optionee shall immediately notify
the Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

            9.    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 California.

            10.   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 (NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE IN ANY WAY 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.

      Optionee acknowledges receipt of a copy of the Plan and represents that he
or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof. Optionee has
reviewed the Plan and this Option 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 or
this Option Agreement. Optionee further agrees to notify the Company upon any
change in the residence address indicated below.

                               SECURITY AGREEMENT

      This Security Agreement is made as of __________, _____ between OneWorld

("Pledgor").

Recitals

      Pursuant to Pledgor's election to purchase Shares under the Option
Agreement dated ________ (the "Option"), between Pledgor and Pledgee under
Pledgee's 1999 Stock Plan, and Pledgor's election under the terms of the Option
to pay for such shares with his promissory note (the "Note"), Pledgor has
purchased _________ shares of Pledgee's Common Stock (the "Shares") at a price
of $________ per share, for a total purchase price of $__________. The Note and
the obligations thereunder are as set forth in Exhibit C to the Option
Agreement.

      NOW, THEREFORE, it is agreed as follows:

      1.    Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Option Agreement, Pledgor,
pursuant to the California Commercial Code, hereby pledges all of such Shares
(herein sometimes referred to as the "Collateral") represented by certificate

herewith delivers said certificate to the Secretary of Pledgee ("Pledgeholder"),
who shall hold said certificate subject to the terms and conditions of this
Security Agreement.

      The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Option, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

      2.    Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

            (a)   Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

            (b)   Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.


<PAGE>   14
            (c)   Margin Regulations. In the event that Pledgee's Common Stock
is now or later becomes margin-listed by the Federal Reserve Board and Pledgee
is classified as a "lender" within the meaning of the regulations under Part 221
of Title 12 of the Code of Federal Regulations ("Regulation U"), Pledgor agrees
to cooperate with Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such regulations.

      3.    Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

      4.    Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

      5.    Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

      6.    Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

            (a)   Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

            (b)   Pledgor fails to perform any of the covenants set forth in the
Option or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

            In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

      7.    Release of Collateral. Subject to any applicable contrary rules
under Regulation U, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial

number of Shares pledged hereunder as the payment of principal bears to the
initial full principal amount of the Note.

      8.    Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

of all indebtedness secured hereby, at which time the remaining pledged stock
shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

      10.   Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

      11.   Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

      12.   Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein

the Optionee:

                  (a)   cash or check; or

                  (b)   consideration received by the Company under a formal
cashless exercise program adopted by the Company in connection with the Plan; or


                                      -2-
<PAGE>   3
                  (c)   surrender of other Shares which, (i) 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 (ii) have a Fair Market
Value on the date of surrender equal to the aggregate Exercise Price of the
Exercised Shares; or

                  (d)   with the Administrator's consent, delivery of Optionee's
promissory note (the "Note") in the form attached hereto as Exhibit C, in the
amount of the aggregate Exercise Price of the Exercised Shares together with the
execution and delivery by the Optionee of the Security Agreement attached hereto
as Exhibit D. The Note shall bear interest at the "applicable federal rate"
prescribed under the Code and its regulations at time of purchase, and shall be
secured by a pledge of the Shares purchased by the Note pursuant to the Security
Agreement.

            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
Law.

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

            7.    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.

            8.    Tax Consequences. 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
aggregate 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 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.

            9.    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 California.

                               SECURITY AGREEMENT

      This Security Agreement is made as of __________, _____ between OneWorld
Systems, Inc., a Delaware corporation ("Pledgee"), and _________________________
("Pledgor").

Recitals

      Pursuant to Pledgor's election to purchase Shares under the Option
Agreement dated ________ (the "Option"), between Pledgor and Pledgee under
Pledgee's 1999 Stock Plan, and Pledgor's election under the terms of the Option
to pay for such shares with his promissory note (the "Note"), Pledgor has
purchased _________ shares of Pledgee's Common Stock (the "Shares") at a price
of $________ per share, for a total purchase price of $__________. The Note and
the obligations thereunder are as set forth in Exhibit C to the Option
Agreement.

      NOW, THEREFORE, it is agreed as follows:

      1.    Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Option Agreement, Pledgor,
pursuant to the California Commercial Code, hereby pledges all of such Shares
(herein sometimes referred to as the "Collateral") represented by certificate
number ______, duly endorsed in blank or with executed stock powers, and
herewith delivers said certificate to the Secretary of Pledgee ("Pledgeholder"),
who shall hold said certificate subject to the terms and conditions of this
Security Agreement.

      The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Option, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

      2.    Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

            (a)   Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

            (b)   Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.


<PAGE>   13
            (c)   Margin Regulations. In the event that Pledgee's Common Stock
is now or later becomes margin-listed by the Federal Reserve Board and Pledgee
is classified as a "lender" within the meaning of the regulations under Part 221
of Title 12 of the Code of Federal Regulations ("Regulation U"), Pledgor agrees
to cooperate with Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such regulations.

      3.    Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

      4.    Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

      5.    Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

      6.    Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

            (a)   Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

            (b)   Pledgor fails to perform any of the covenants set forth in the
Option or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

            In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

      7.    Release of Collateral. Subject to any applicable contrary rules
under Regulation U, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of


                                      -2-
<PAGE>   14


Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

      8.    Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

      9.    Term. The within pledge of Shares shall continue until the payment
of all indebtedness secured hereby, at which time the remaining pledged stock
shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

      10.   Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

      11.   Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

      12.   Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

      13.   Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein

successors, assigns, heirs, executors and administrators.

                  [Wilson Sonsini Goodrich & Rosati Letterhead]

        RE:  REGISTRATION STATEMENT OF FORM S-8

Gentlemen:

        We have examined the Registration Statement on Form S-8 to be filed by
you with the Securities and Exchange Commission on or about August 31, 1999 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 1,165,000 shares of your Common Stock
reserved for issuance under the 1999 Stock Plan (the "1999 Plan"). As your legal
counsel, we have examined the proceedings taken and are familiar with the
proceedings proposed to be taken by you in connection with the sale and issuance
of such Common Stock under the 1999 Plan.

        It is our opinion that, when issued and sold in the manner referred to
in the 1999 Plan and pursuant to the agreements which accompany the 1999 Plan,
the Common Stock issued and sold thereby will be legally and validly issued,
fully paid and non-assessable.

        We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including any Prospectus constituting a part thereof,
and any amendments thereto. This opinion may be incorporated by reference in any
abbreviated registration statement filed pursuant to Rule 462 under the
Securities Act with respect to the Registration Statement.

                                   Very truly yours,

                                   WILSON SONSINI GOODRICH & ROSATI
