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

                               NOTICE OF EXERCISE
                               ------------------

         THIS AGREEMENT is dated as of ___________, ____, between LMKI, Inc.
(the "Company"), and _________________ ("Purchaser").

                              W I T N E S S E T H:

         WHEREAS, the Company and Purchaser are parties to that certain ___
Incentive ___ Nonstatutory Stock Option Agreement dated as of ___________, ____
(the "Option Agreement") pursuant to which the Purchaser has the right to
purchase up to ______ shares of the Company's common stock (the "Option
Shares"); and

         WHEREAS, the Option is exercisable with respect to certain of the
Option Shares as of the date hereof; and

         WHEREAS, pursuant to the Option Agreement, Purchaser desires to
purchase shares of the Company as herein described, on the terms and conditions
set forth in this Agreement, the Option Agreement and the LMKI, Inc. Amended and
Restated 1999 Stock Option Plan (the "Plan"). Certain capitalized terms used in
this Agreement are defined in the Plan.

         NOW, THEREFORE, it is agreed between the parties as follows:

SECTION 1: PURCHASE OF SHARES.

         Pursuant to the terms of the Option Agreement, Purchaser hereby agrees
to purchase from the Company and the Company agrees to sell and issue to
Purchaser _________ shares of the Company's common stock (the "Stock") for the
Exercise Price per share specified in the Option Agreement payable by personal
check, cashier's check or money order, if permitted by the Option Agreement, as
follows: _______________________________. Payment shall be delivered at the

                  (B) REPURCHASE OPTION

         All unvested shares of the Stock purchased by the Purchaser pursuant to
this Agreement (sometimes referred to as the "Repurchase Option Stock") shall be
subject to the following option (the "Repurchase Option"):

         In the event the Purchaser terminates service with the Company
("Service") for any reason, with or without cause, the Company may exercise the
Repurchase Option.

         Purchaser understands that the Stock is being sold in order to induce
Purchaser to become and/or remain associated with the Company and to work
diligently for the success of the Company and that the Repurchase Option Stock
will continue to vest in accordance with the schedule set forth in the Option
Agreement. Accordingly, the Company shall have the right at any time within 90
days after the termination of Service to purchase from the Purchaser all shares
of Stock purchased hereunder which have not vested in accordance with the terms
of such vesting schedule in the Option Agreement. The purchase price for such
unvested shares of Repurchase Option Stock shall be the Exercise Price per share
paid by Purchaser for such shares pursuant to the Option (the "Option Price").
The purchase price shall be paid by certified or cashier's check or by
cancellation of any indebtedness of Purchaser to the Company.

         Nothing in this Agreement shall be construed as a right by purchaser to
be employed by Company, or a parent or subsidiary of Company.

                  (C) EXERCISE OF REPURCHASE OPTION

         The Repurchase Option shall be exercised by written notice signed by an
officer of the Company and delivered or mailed as provided in Section 16 of this
Agreement and to the Escrow Agent as provided in Section 16 of the Joint Escrow
Instructions attached as Exhibit B to the Option Agreement.

                  (D) WAIVER, ASSIGNMENT, EXPIRATION OF REPURCHASE OPTION

         If the Company waives or fails to exercise the Repurchase Option as to
all of the shares subject thereto, the Company may, in the discretion of its
Board of Directors, assign the Repurchase Option to any other holder or holders
of preferred or common stock of the Company in such proportions as such Board of
Directors may determine. In the event of such an assignment, the assignee shall
pay to the Company in cash an amount equal to the fair market value of the
Repurchase Option. The Company shall promptly, upon expiration of the 90-day
period referred to in Section 2 above, notify Purchaser of the number of shares
subject to the Repurchase Option assigned to such stockholders and shall notify
both the Purchaser and the assignees of the time, place and date for settlement
of such purchase, which must be made within 90 days from the date of cessation
of continuous employment. In the event that the Company and/or such assignees do
not elect to exercise the Repurchase Option as to all or part of the shares
subject to it, the Repurchase Option shall expire as to all shares which the
Company and/or such assignees have not elected to purchase.

                  (E) ESCROW OF SHARES

         As security for Purchaser's faithful performance of the terms of this
Agreement and to ensure the availability for delivery of Purchaser's shares upon
exercise of the Repurchase Option herein provided for, Purchaser agrees at the
Closing hereunder, to deliver to and deposit with the Escrow Agent named in the
Joint Escrow Instructions attached to the Option Agreement as Exhibit B, the
certificate or certificates evidencing the Option Stock subject to the
Repurchase Option and two Assignments Separate from Certificate duly executed
(with date and number of shares in blank) in the form attached to the Option
Agreement as Exhibit D. Such documents are to be held by the Escrow Agent and
delivered by the Escrow Agent pursuant to the Joint Escrow Instructions, which
instructions shall also be delivered to the Escrow Agent at the Closing
hereunder.

         Within 30 days after the last day of each successive completed calendar
quarter after the Closing Date, if Purchaser so requests, the Escrow Agent will
deliver to Purchaser certificates representing so many shares of Stock as are no
longer subject to the Repurchase Option (less such shares as have been
previously delivered). Ninety days after cessation of Purchaser's employment
with the Company the Company will direct the Escrow Agent to deliver to
Purchaser a certificate or certificates representing the number of shares not
repurchased by the Company or its assignees pursuant to exercise of the
Repurchase Option (less such shares as have been previously delivered).

                  (F) ADJUSTMENT OF SHARES

         Subject to the provisions of the Articles of Incorporation of the
Company, if, from time to time during the term of the Repurchase Option:

         (i) there is any stock dividend or liquidating dividend of cash and/or
property, stock split or other change in the character or amount of any of the
outstanding securities of the Company, or

         (ii) there is any consolidation, merger or sale of all or substantially
all, of the assets of the Company,

         then, in such event, any and all new, substituted or additional
securities or other property to which Purchaser is entitled by reason of
Purchaser's ownership of the shares shall be immediately subject to such
Repurchase Option with the same force and effect as the shares of Option Stock
from time to time subject to the Repurchase Option. While the total Option Price
shall remain the same after each such event, the Option Price per share of
Option Stock upon exercise of the Repurchase Option shall be appropriately and
equitably adjusted as determined by the Board of Directors of the Company.

                  (G) THE COMPANY'S RIGHT OF FIRST REFUSAL.

         Before any shares of Stock registered in the name of Purchaser and not
subject to the Repurchase Option may be sold or transferred, such shares shall
first be offered to the Company as set forth in the Option Agreement.

                                      -3-
<PAGE>

                  (H) PURCHASER'S RIGHTS AFTER EXERCISE OF REPURCHASE OPTION OR
                  RIGHT OF FIRST REFUSAL.

         If the Company makes available, at the time and place and in the amount
and form provided in this Agreement, the consideration for the Stock to be
repurchased in accordance with the provisions of Sections 2 and 7 of this
Agreement, then from and after such time the person from whom such shares are to
be repurchased shall no longer have any rights as a holder of such shares (other
than the right to receive payment of such consideration in accordance with this
Agreement). Such shares shall be deemed to have been repurchased in accordance
with the applicable provisions hereof, whether or not the certificate(s)
therefor have been delivered as required by this Agreement.

                  (I) TRANSFER BY PURCHASER TO CERTAIN TRUSTS.

         Purchaser shall have the right to transfer all or any portion of
Purchaser's interest in the shares issued under this Agreement which have been
delivered to Purchaser under the provisions of Section 5 of this Agreement, to a
trust established by Purchaser for the benefit of Purchaser, Purchaser's spouse
or Purchaser's children, without being subject to the provisions of Section 7
hereof, provided that the trustee on behalf of the trust shall agree in writing
to be bound by the terms and conditions of this Agreement. The transferee shall
execute a copy of Exhibit C attached to the Option Agreement and file the same
with the Secretary of the Company.

                  (J) LEGEND OF SHARES.

         All certificates representing the Stock purchased under this Agreement
shall, where applicable, have endorsed thereon the legends set forth in the
Option Agreement and any other legends required by applicable securities laws.

                  (K) PURCHASER'S INVESTMENT REPRESENTATIONS.

         This Agreement is made with Purchaser in reliance upon Purchaser's
representation to the Company, which by Purchaser's acceptance hereof Purchaser
confirms, that the Stock which Purchaser will receive will be acquired with
Purchaser's own funds for investment for an indefinite period for Purchaser's
own account, not as a nominee or agent, and not with a view to the sale or
distribution of any part thereof, and that Purchaser has no present intention of
selling, granting participation in, or otherwise distributing the same, but
subject, nevertheless, to any requirement of law that the disposition of
Purchaser's property shall at all times be within Purchaser's control. By
executing this Agreement, Purchaser further represents that Purchaser does not
have any contract, understanding or agreement with any person to sell, transfer,
or grant participation, to such person or to any third person, with respect to
any of the Stock.

         Purchaser understands that the Stock will not be registered or
qualified under federal or state securities laws on the ground that the sale
provided for in this Agreement is exempt from registration or qualification
under federal or state securities laws and that the Company's reliance on such
exemption is predicated on Purchaser's representations set forth herein.

                                      -4-
<PAGE>

         Purchaser agrees that in no event will Purchaser make a disposition of
any of the Stock (including a disposition under Section 9 of this Agreement),
unless and until (i) Purchaser shall have notified the Company of the proposed
disposition and shall have furnished the Company with a statement of the
circumstances surrounding the proposed disposition and (ii) Purchaser shall have
furnished the Company with an opinion of counsel satisfactory to the Company to
the effect that (A) such disposition will not require registration or
qualification of such Stock under federal or state securities laws or (B)
appropriate action necessary for compliance with the federal or state securities
laws has been taken or (iii) the Company shall have waived, expressly and in
writing, its rights under clauses (i) and (ii) of this section.

         With respect to a transaction occurring prior to such date as the Plan
and Stock thereunder are covered by a valid Form S-8 or similar federal
registration statement, this subsection shall apply unless the transaction is
covered by the exemption in California Corporations Code ss.25102(o) or a
similar broad based exemption. In connection with the investment representations
made herein, Purchaser represents that Purchaser is able to fend for himself or
herself in the transactions contemplated by this Agreement, has such knowledge
and experience in financial and business matters as to be capable of evaluating
the merits and risks of Purchaser's investment, has the ability to bear the
economic risks of Purchaser's investment and has been furnished with and has had
access to such information as would be made available in the form of a
registration statement together with such additional information as is necessary
to verify the accuracy of the information supplied and to have all questions
answered by the Company.

         Purchaser understands that if the Company does not register with the
Securities and Exchange Commission pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") or if a registration
statement covering the Stock (or a filing pursuant to the exemption from
registration under Regulation A of the Securities Act of 1933) under the
Securities Act of 1933 is not in effect when Purchaser desires to sell the
Stock, Purchaser may be required to hold the Stock for an indeterminate period.
Purchaser also acknowledges that Purchaser understands that any sale of the
Stock which might be made by Purchaser in reliance upon Rule 144 under the
Securities Act of 1933 may be made only in limited amounts in accordance with
the terms and conditions of that Rule.

                  (L) ASSISTANCE TO PURCHASER UNDER RULE 144.

         The Company covenants and agrees that (a) at all times after it first
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act, it will use its best efforts to comply with the current public
information requirements of Rule 144(c)(1) under the Securities Act of 1933, and
that if prior to becoming subject to such reporting requirements an
over-the-counter market develops for the Stock, it will make publicly available
the information required by Rule 144(c)(2); (b) it will furnish Purchaser, upon
request, with all information required for the preparation and filing of Form
144; and (c) it will on a timely basis use its best efforts to file all reports
required to be filed and make all disclosures, including disclosures of
materially adverse information, required to permit Purchaser to make the
required representations in Form 144.

<PAGE>

                  (M) NO DUTY TO TRANSFER IN VIOLATION HEREUNDER.

         The Company shall not be required (a) to transfer on its books any
shares of Stock of the Company which shall have been sold or transferred in
violation of any of the provisions set forth in this Agreement or (b) to treat
as owner of such shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such shares shall have been so transferred.

                  (N) RIGHTS OF PURCHASER.

         Except as otherwise provided herein, Purchaser shall, during the term
of this Agreement, exercise all rights and privileges of a stockholder of the
Company with respect to the Stock.

                  (O) OTHER NECESSARY ACTIONS.

         The parties agree to execute such further instruments and to take such
further action as may reasonably be necessary to carry out the intent of this
Agreement.

                  (P) NOTICE.

         Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon the earliest of personal delivery,
receipt or the third full day following deposit in the United States Post Office
with postage and fees prepaid, addressed to the other party hereto at the
address last known or at such other address as such party may designate by 10
days' advance written notice to the other party hereto.

                  (Q) SUCCESSORS AND ASSIGNS.

         This Agreement shall inure to the benefit of the successors and assigns
of the Company and, subject to the restrictions on transfer herein set forth, be
binding upon Purchaser and Purchaser's heirs, executors, administrators,
successors and assigns. The failure of the Company in any instance to exercise
the Repurchase Option or rights of first offer described herein shall not
constitute a waiver of any other Repurchase Option or right of first offer that
may subsequently arise under the provisions of this Agreement. No waiver of any
breach or condition of this Agreement shall be deemed to be a waiver of any
other or subsequent breach or condition, whether of a like or different nature.

                  (R) APPLICABLE LAW.

         This Agreement shall be governed by, and construed in accordance with,
the laws of the State of California, as such laws are applied to contracts
entered into and performed in such state.

                  (S) NO STATE QUALIFICATION.

         THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS
NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF
CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY
PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL,
UNLESS THE SALE OF SECURITIES IS EXEMPT FROM THE QUALIFICATION BY SECTION 25100,
25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO
THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED,
UNLESS THE SALE IS SO EXEMPT.

and final agreement between the parties hereto with regard to the subject matter
hereof.

Secretary

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

Dear Sir or Madam:

         As Escrow Agent for both LMKI, Inc. (the "Company"), and
___________________ ("Purchaser"), you are hereby authorized and directed to
hold the documents delivered to you pursuant to the terms of that certain Common
Stock Purchase Agreement (the "Agreement") of even date herewith, to which a
copy of these Joint Escrow Instructions is attached as Exhibit B to a certain
Stock Option dated ________ ("Option Agreement"), in accordance with the
following instructions:

         In the event the Company shall elect to exercise the Repurchase Option
set forth in the Agreement, the Company shall give to Purchaser and you a
written notice as provided in the Agreement. Purchaser and the Company hereby
irrevocably authorize and direct you to close the transaction contemplated by
such notice, including prompt delivery of stock certificates.

         At the closing, you are directed (a) to date the stock assignment form
or forms necessary for the transfer in question, (b) to fill in the number of
shares being transferred, and (c) to deliver same, together with the certificate
or certificates evidencing the shares to be transferred, to the Company against
the simultaneous delivery to you of the purchase price (by certified or bank
cashier's check) for the number of shares being purchased pursuant to the
exercise of the Repurchase Option.

         Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares to be held by you hereunder and any additions and
substitutions to said shares as defined in the Agreement. Purchaser does hereby
irrevocably constitute and appoint you as Purchaser's attorney-in-fact and agent
for the term of this escrow to execute with respect to such securities all
documents necessary or appropriate to make such securities negotiable and to
complete any transaction herein contemplated. Subject to the provisions of this
Section 3, Purchaser shall exercise all rights and privileges, including but not
limited to, the right to vote and to receive dividends (if any), of a
stockholder of the Company while the shares are held by you.

         In accordance with the terms of Section 5 of the Agreement, you may
from time to time deliver to Purchaser a certificate or certificates
representing so many shares as are no longer subject to the Repurchase Option.

         This escrow shall terminate upon the release of all shares held under
the terms and provisions hereof.

                                      -1-
<PAGE>

         If at the time of termination of this escrow you should have in your
possession any documents, securities or other property belonging to Purchaser,
you shall deliver all of same to Purchaser and shall be discharged from all
further obligations hereunder.

         Your duties hereunder may be altered, amended, modified or revoked only
by a writing signed by all of the parties hereto.

         You shall be obligated only for the performance of such duties as are
specifically set forth herein and may rely and shall be protected in relying or
refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact of Purchaser while acting in good faith and
in the exercise of your own good judgment, and any act done or omitted by you
pursuant to the advice of your own attorneys shall be conclusive evidence of
such good faith.

         You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law, and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court. In
case you obey or comply with any such order, judgment or decree of any court,
you shall not be liable to any of the parties hereto or to any other person,
firm or corporation by reason of such compliance, notwithstanding any such
order, judgment or decree being subsequently reversed, modified, annulled, set
aside, vacated or found to have been entered without jurisdiction.

         You shall not be liable in any respect on account of the identity,
authority or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

         You shall not be liable for the outlawing of any rights under any
statute of limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

         You shall be entitled to employ such legal counsel and other experts as
you may deem necessary properly to advise you in connection with your
obligations hereunder and may rely upon the advice of such counsel.

         Your responsibilities as Escrow Agent hereunder shall terminate if you
shall cease to be Secretary of the Company or if you shall resign by written
notice of each party. In the event of any such termination, the Company shall
appoint any officer of the Company as successor Escrow Agent.

         If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

                                      -2-
<PAGE>

         It is understood and agreed that should any dispute arise with respect
to the delivery and/or ownership or right of possession of the securities held
by you hereunder, you are authorized and directed to retain in your possession
without liability to anyone all or any part of said securities until such
dispute shall have been settled either by mutual written agreement of the
parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

         Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in
the United States Post Office, by registered or certified mail with postage and
fees prepaid, addressed to each of the other parties thereunto entitled.

only for the purpose of said Joint Escrow Instructions; you do not become a
party to the Agreement.

                        LMKI, INC. 2000 STOCK OPTION PLAN
                        ---------------------------------

1. PURPOSE.
-----------

         The purpose of the 2000 Stock Option Plan (the "Plan") is to offer
selected employees, directors and consultants an opportunity to acquire a
proprietary interest in the success of the Company, or to increase such
interest, to encourage such selected persons to remain in the employ of the
Company and to attract new employees with outstanding qualifications. The Plan
seeks to achieve this purpose by providing for Awards in the form of Restricted
Shares and Options (which may constitute Incentive Stock Options or Nonstatutory
Stock Options) as well as the direct award or sale of Shares of the Company's
Common Stock. While this Plan is intended to satisfy federal Rule 701 and
Section 25102(o) of the California Corporations Code, awards may be granted
under this Plan in reliance upon other federal and state securities law
exemptions and to the extent another exemption is relied upon, the terms of this
Plan which are required only because of Rule 701 or Section 25102(o) need not
apply to the extent provided by the Committee in the award agreement.

2. DEFINITIONS.

         (a) "AWARD" shall mean any award of an Option, Restricted Share or
other right under the Plan.

         (b) "BOARD OF DIRECTORS" shall mean the Board of Directors of the
Company, as constituted from time to time.

         (c) "CHANGE IN CONTROL" shall mean:

                  (1) The consummation of a merger, consolidation, sale of the
         Company's stock, or other reorganization of the Company (other than a
         reincorporation of the Company), if after giving effect to such merger,
         consolidation or other reorganization of the Company, the stockholders
         of the Company immediately prior to such merger, consolidation or other
         reorganization do not represent a majority interest of the holders of
         voting securities (on a fully diluted basis) with the ordinary voting
         power to elect directors of the surviving or resulting entity after
         such merger, consolidation or other reorganization; or

                  (2) The sale of all or substantially all of the assets of the
         Company to a third party who is not an affiliate of the Company.

Employee and, for that reason, has not paid such individual in a manner which
results in the issuance of a Form W-2 and withheld taxes with respect to him or

considered employment for all purposes of the Plan except the second sentence of
Section 4(a).

         (i) "EXCHANGE ACT" means the Securities and Exchange Act of 1934, as
amended.

         National Market System, then the Fair Market Value shall be equal to
         the mean between the last reported representative bid and asked prices
         quoted for such date by the principal automated inter-dealer quotation
         system on which the Shares are quoted or, if the Shares are not quoted
         on any such system, by the "Pink Sheets" published by the National
         Quotation Bureau, Inc.;

         question and were traded on the Nasdaq Stock Market or the Nasdaq

         the last-transaction price quoted for such date by the Nasdaq Stock
         Market or the Nasdaq National Market;

                  (3) If the Shares were traded on a stock exchange on the date
         in question, then the Fair Market Value shall be equal to the closing
         price reported by the applicable composite transactions report for such
         date; and

                  (4) If none of the foregoing provisions is applicable, then
         the Fair Market Value shall be determined by the Committee in good
         faith on such basis as it deems appropriate.

         In all cases, the determination of Fair Market Value by the Committee
shall be conclusive and binding on all persons.

3. ADMINISTRATION.
------------------

         (a) COMMITTEE MEMBERSHIP. The Plan shall be administered by the
Compensation Committee (the "Committee") appointed by the Company's Board of
Directors and comprised of at least two or more Outside Directors (although
Committee functions may be delegated to officers to the extent the awards relate
to persons who are not subject to the reporting requirements of Section 16 of
the Exchange Act). If no Committee has been appointed, the entire Board shall

the members of the Committee as chairperson. The Committee may hold meetings at
such times and places as it shall determine. The acts of a majority of the
Committee members present at meetings at which a quorum exists, or acts reduced
to or approved in writing by all Committee members, shall be valid acts of the
Committee.

         (c) COMMITTEE RESPONSIBILITIES. The Committee has and may exercise such
power and authority as may be necessary or appropriate for the Committee to
carry out its functions as described in the Plan. The Committee has authority in
its discretion to determine eligible Employees to whom, and the time or times at
which, Awards may be granted and the number of Shares subject to each Award.
Subject to the express provisions of the respective Award agreements (which need

                                      -5-
<PAGE>

not be identical) and to make all other determinations necessary or advisable
for Plan administration, the Committee has authority to prescribe, amend, and
rescind rules and regulations relating to the Plan. All interpretations,
determinations, and actions by the Committee will be final, conclusive, and
binding upon all persons.

         (d) COMMITTEE LIABILITY. No member of the Board or the Committee will
be liable for any action or determination made in good faith by the Committee
with respect to the Plan or any Award made under the Plan.

not less often than annually, the Company shall furnish to Offerees, Optionees
and Shareholders who have received Stock under the Plan its financial statements
including a balance sheet regarding the Company's financial condition and
results of operations, unless such Offerees, Optionees or Shareholders have
duties with the Company that assure them access to equivalent information. Such
financial statements need not be audited.

4. ELIGIBILITY.
---------------

         (a) GENERAL RULE. Only Employees shall be eligible for designation as
Participants by the Committee. In addition, only individuals who are employed as
Common-Law Employees by the Company or a Subsidiary shall be eligible for the
grant of ISOs.

         (b) TEN-PERCENT SHAREHOLDERS. An Employee who owns more than ten
percent (10%) of the total combined voting power of all classes of outstanding
stock of the Company or any of its Subsidiaries shall not be eligible for
designation as an Offeree or Optionee unless (i) the Exercise Price for an ISO
(and a NSO to the extent required by applicable law) is at least one hundred ten
percent (110%) of the Fair Market Value of a Share on the date of grant, (ii) if
required by applicable law, the Purchase Price of Shares is at least one hundred
percent (100%) of the Fair Market Value of a Share on the date of grant, and
(iii) in the case of an ISO, such ISO by its terms is not exercisable after the
expiration of five years from the date of grant.

         (c) ATTRIBUTION RULES. For purposes of Subsection (b) above, in
determining stock ownership, an Employee shall be deemed to own the stock owned,
directly or indirectly, by or for his brothers, sisters, spouse, ancestors and
lineal descendants. Stock owned, directly or indirectly, by or for a
corporation, partnership, estate or trust shall be deemed to be owned
proportionately by or for its shareholders, partners or beneficiaries. Stock
with respect to which such Employee holds an Option shall not be counted.

                                      -6-

         (d) OUTSTANDING STOCK. For purposes of Subsection (b) above,
"outstanding stock" shall include all stock actually issued and outstanding
immediately after the grant. "Outstanding Stock" shall not include shares
authorized for issuance under outstanding Options held by the Employee or by any
other person.

5. STOCK SUBJECT TO PLAN.
-------------------------

         (a) BASIC LIMITATION. Shares offered under the Plan shall be authorized
but unissued Shares. Subject to Sections 5(b) and 9 of the Plan, the aggregate
number of Shares which may be issued or transferred as common stock pursuant to
an Award under the Plan shall not exceed 5,000,000 Shares.

         In any event, (i) the number of Shares which are subject to Awards or
other rights outstanding at any time under the Plan shall not exceed the number
of Shares which then remain available for issuance under the Plan; and (ii) to
the extent an award is made in reliance upon the exemption available under
Section 25102(o) of the California Corporations Code, the number of Shares which
are subject to Awards or other rights outstanding at any time under the Plan or
otherwise shall not exceed the limitation imposed by Section 260.140.45 of Title
10 of the California Code of Regulations. The Company, during the term of the
Plan, shall at all times reserve and keep available sufficient Shares to satisfy
the requirements of the Plan.

         (b) ADDITIONAL SHARES. In the event that any outstanding Option or
other right for any reason expires or is canceled or otherwise terminated, the
Shares allocable to the unexercised portion of such Option or other right shall
again be available for the purposes of the Plan. If a Restricted Share is
forfeited before any dividends have been paid with respect to such Restricted
Share, then such Restricted Share shall again become available for award under
the Plan.

6. TERMS AND CONDITIONS OF AWARDS OR SALES.
-------------------------------------------

         (a) STOCK PURCHASE AGREEMENT. Each award or sale of Shares under the
Plan (other than upon exercise of an Option) shall be evidenced by a Stock
Purchase Agreement between the Offeree and the Company. Such award or sale shall
be subject to all applicable terms and conditions of the Plan and may be subject
to any other terms and conditions which are not inconsistent with the Plan and
which the Committee deems appropriate for inclusion in a Stock Purchase
Agreement. The provisions of the various Stock Purchase Agreements entered into
under the Plan need not be identical.

                                      -7-
<PAGE>

         (b) DURATION OF OFFERS. Any right to acquire Shares under the Plan
(other than an Option) shall automatically expire if not exercised by the

Offeree by the Committee.

         (c) PURCHASE PRICE. Unless otherwise permitted by applicable law, the
Purchase Price of Shares to be offered under the Plan shall not be less than
eighty-five percent (85%) of the Fair Market Value of a Share on the date of
grant (100% for 10% shareholders), except as otherwise provided in Section 4(b).
Subject to the preceding sentence, the Purchase Price shall be determined by the
Committee in its sole discretion. The Purchase Price shall be payable in a form
described in Subsection (d) below.

         (d) PAYMENT FOR SHARES. The entire Purchase Price of Shares issued
under the Plan shall be payable in lawful money of the United States of America
at the time when such Shares are purchased, except as provided below:

                  (1) SURRENDER OF STOCK. To the extent that a Stock Option
         Agreement so provides, payment may be made all or in part with Shares
         which have already been owned by the Optionee or Optionee's
         representative for any time period specified by the Committee and which
         are surrendered to the Company in good form for transfer. Such shares
         shall be valued at their Fair Market Value on the date when the new
         Shares are purchased under the Plan.

                  (2) PROMISSORY NOTES. To the extent that a Stock Option
         Agreement or Stock Purchase Agreement so provides, payment may be made
         all or in part with a full recourse promissory note executed by the
         Optionee or Offeree. The interest rate and other terms and conditions
         of such note shall be determined by the Committee. The Committee may
         require that the Optionee or Offeree pledge his or her Shares to the
         Company for the purpose of securing the payment of such note. In no
         event shall the stock certificate(s) representing such Shares be
         released to the Optionee or Offeree until such note is paid in full.

                  (3) CASHLESS EXERCISE. To the extent that a Stock Option
         Agreement so provides and a public market for the Shares exists,
         payment may be made all or in part by delivery (on a form prescribed by
         the Committee) of an irrevocable direction to a securities broker to
         sell shares and to deliver all or part of the sale proceeds to the
         Company in payment of the aggregate Exercise Price.

                  (4) OTHER FORMS OF PAYMENT. To the extent provided in the
         Stock Option Agreement, payment may be made in any other form that is
         consistent with applicable laws, regulations and rules.

<PAGE>

         (e) EXERCISE OF AWARDS ON TERMINATION OF SERVICE. Each Stock Award
Agreement shall set forth the extent to which the recipient shall have the right
to exercise the Award following termination of the recipient's Service with the
Company and its Subsidiaries. Such provisions shall be determined in the sole
discretion of the Committee, need not be uniform among all the Awards issued
pursuant to the Plan, and may reflect distinctions based on the reasons for
termination of employment.

7. ADDITIONAL TERMS AND CONDITIONS OF RESTRICTED SHARES.
--------------------------------------------------------

         (a) FORM AND AMOUNT OF AWARD. Each Stock Award Agreement shall specify
the number of Shares that are subject to the Award. Restricted Shares may be
awarded in combination with NSOs and such an Award may provide that the
Restricted Shares will be forfeited in the event that the related NSOs are
exercised.

         (b) EXERCISABILITY. Each Stock Award Agreement shall specify the
conditions upon which Restricted Shares shall become vested, in full or in
installments. To the extent required by applicable law, each Stock Award shall
become exercisable no less rapidly than the rate of 20% per year for each of the
first five years from the date of grant. Subject to the preceding sentence, the
exercisability of any Stock Award shall be determined by the Committee in its
sole discretion.

         (c) EFFECT OF CHANGE IN CONTROL. The Committee may determine at the
time of making an Award or thereafter, that such Award shall become fully
vested, in whole or in part, in the event that a Change in Control occurs with
respect to the Company.

         (d) VOTING RIGHTS. Holders of Restricted Shares awarded under the Plan
shall have the same voting, dividend and other rights as the Company's other
stockholders. A Stock Award Agreement, however, may require that the holders
invested any cash dividends received in additional Restricted Shares. Such
additional Restricted Shares shall be subject to the same conditions and
restrictions as the Award with respect to which the dividends were paid. Such
additional Restricted Shares shall not reduce the number of Shares available
under Section 5.

8. TERMS AND CONDITIONS OF OPTIONS.
-----------------------------------

         (a) STOCK OPTION AGREEMENT. Each grant of an Option under the Plan
shall be evidenced by a Stock Option Agreement between the Optionee and the
Company. Such Option shall be subject to all applicable terms and conditions of
the Plan and may be subject to any other terms and conditions which are not
inconsistent with the Plan and which the Committee deems appropriate for
inclusion in a Stock Option Agreement. The provisions of the various Stock
Option Agreements entered into under the Plan need not be identical.

         (b) NUMBER OF SHARES. Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 9. The Stock Option
Agreement shall also specify whether the Option is an ISO or a Nonstatutory
Option.

         (c) EXERCISE PRICE. Each Stock Option Agreement shall specify the
Exercise Price. The Exercise Price of an ISO shall not be less than one hundred
percent (100%) of the Fair Market Value of a Share on the date of grant, except
as otherwise provided in Section 4(b). To the extent required by applicable law
and except as otherwise provided in Section 4(b), the Exercise Price of a
Nonstatutory Option shall not be less than eighty-five percent (85%) of the Fair
Market Value of a Share on the date of grant. Subject to the preceding two
sentences, the Exercise Price under any Option shall be determined by the
Committee in its sole discretion. The Exercise Price shall be payable in a form
described in Subsection (h) below.

         (d) EXERCISABILITY. Each Stock Option Agreement shall specify the date
when all or any installment of the Option is to become exercisable. To the
extent required by applicable law, an Option shall become exercisable no less
rapidly than the rate of 20% per year for each of the first five years from the
date of grant. Subject to the preceding sentence, the exercisability of any
Option shall be determined by the Committee in its sole discretion.

         (e) EFFECT OF CHANGE IN CONTROL. The Committee may determine, at the
time of granting an Option or thereafter, that such Option shall become fully
exercisable as to all Shares subject to such Option in the event that a Change
in Control occurs with respect to the Company.

         (f) TERM. The Stock Option Agreement shall specify the term of the
Option. The term shall not exceed ten years from the date of grant (or five (5)
years for ten percent (10%) shareholders as provided in Section 4(b)). Subject
to the preceding sentence, the Committee at its sole discretion shall determine
when an Option is to expire.

                                      -10-

         (g) EXERCISE OF OPTIONS ON TERMINATION OF SERVICE. Each Option shall
set forth the extent to which the Optionee shall have the right to exercise the
Option following termination of the Optionee's Service with the Company and its
Subsidiaries. Such provisions shall be determined in the sole discretion of the
Committee, need not be uniform among all Options issued pursuant to the Plan,
and may reflect distinctions based on the reasons for termination of employment.
Notwithstanding the foregoing, to the extent required by applicable law, each
Option shall provide that the Optionee shall have the right to exercise the
vested portion of any Option held at termination for at least 60 days following
termination of Service with the Company for any reason, and that the Optionee
shall have the right to exercise the Option for at least six months if the
Optionee's Service terminates due to death or Disability.

         (h) PAYMENT OF OPTION SHARES. The entire Exercise Price of Shares
issued under the Plan shall be payable in lawful money of the United States of
America at the time when such Shares are purchased, except as provided below:

                  (1) SURRENDER OF STOCK. To the extent that a Stock Option
         Agreement so provides, payment may be made all or in part with Shares
         which have already been owned by the Optionee or Optionee's
         representative for any time period specified by the Committee and which
         are surrendered to the Company in good form for transfer. Such shares
         shall be valued at their Fair Market Value on the date when the new
         Shares are purchased under the Plan.

                  (2) PROMISSORY NOTES. To the extent that a Stock Option
         Agreement or Stock Purchase Agreement so provides, payment may be made
         all or in part with a full recourse promissory note executed by the
         Optionee or Offeree. The interest rate and other terms and conditions
         of such note shall be determined by the Committee. The Committee may
         require that the Optionee or Offeree pledge his or her Shares to the
         Company for the purpose of securing the payment of such note. In no
         event shall the stock certificate(s) representing such Shares be
         released to the Optionee or Offeree until such note is paid in full.

                  (3) CASHLESS EXERCISE. To the extent that a Stock Option
         Agreement so provides and a public market for the Shares exists,
         payment may be made all or in part by delivery (on a form prescribed by
         the Committee) of an irrevocable direction to a securities broker to
         sell shares and to deliver all or part of the sale proceeds to the
         Company in payment of the aggregate Exercise Price.

                  (4) OTHER FORMS OF PAYMENT. To the extent provided in the
         Stock Option Agreement, payment may be made in any other form that is
         consistent with applicable laws, regulations and rules.

         (j) MODIFICATION, EXTENSION AND ASSUMPTION OF OPTIONS. Within the
limitations of the Plan, the Committee may modify, extend or assume outstanding
Options or may accept the cancellation of outstanding Options (whether granted
by the Company or another issuer) in return for the grant of new Options for the
same or a different number of Shares and at the same or a different Exercise
Price or for other consideration.

9. ADJUSTMENT OF SHARES.
------------------------

         (a) GENERAL. In the event of a subdivision of the outstanding Stock, a
declaration of a dividend payable in Shares, a combination or consolidation of
the outstanding Stock into a lesser number of Shares, a recapitalization, a
reclassification or a similar occurrence, the Committee shall make appropriate
adjustments, subject to the limitations set forth in Section 9(c), in one or
more of (i) the number of Shares available for future Awards under Section 5,
(ii) the number of Shares covered by each outstanding Option or Purchase
Agreement or (iii) the Exercise Price or Purchase Price under each outstanding
Option or Stock Purchase Agreement.

         (b) REORGANIZATIONS. In the event that the Company is a party to a
merger or reorganization, outstanding Options shall be subject to the agreement
of merger or reorganization, provided however, that the limitations set forth in
Section 9(c) shall apply.

         (c) RESERVATION OF RIGHTS. Except as provided in this Section 9, an
Optionee or an Offeree shall have no rights by reason of (i) any subdivision or
consolidation of shares of stock of any class, (ii) the payment of any dividend
or (iii) any other increase or decrease in the number of shares of stock of any
class. Any issue by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall not affect, and no
adjustment by reason thereof shall be made with respect to, the number, Exercise
Price or Purchase Agreement of Shares subject to an Option or Stock Purchase
Agreement. The grant of an Award pursuant to the Plan shall not affect in any
way the right or power of the Company to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure, to merge or
consolidate or to dissolve, liquidate, sell or transfer all or any part of its
business or assets.

10. WITHHOLDING TAXES.
----------------------

         (a) GENERAL. To the extent required by applicable federal, state, local
or foreign law, a Participant or his or her successor shall make arrangements
satisfactory to the Committee for the satisfaction of any withholding tax
obligations that arise in connection with the Plan. The Company shall not be
required to issue any Shares or make any cash payment under the Plan until such
obligations are satisfied.

         (b) SHARE WITHHOLDING. The Committee may permit a Participant to
satisfy all or part of his or her withholding or income tax obligations by
having the Company withhold all or a portion of any Shares that otherwise would
be issued to him or her or by surrendering all or a portion of any Shares that
he or she previously acquired. Such Shares shall be valued at their Fair Market
Value on the date when taxes otherwise would be withheld in cash. Any payment of
taxes by assigning Shares to the Company may be subject to restrictions,
including any restrictions required by rules of any federal or state regulatory
body or other authority.

                                      -12-
<PAGE>

         (c) CASHLESS EXERCISE/PLEDGE. The Committee may provide that if Company
Shares are publicly traded at the time of exercise, arrangements may be made to
meet the Optionee's withholding obligation by cashless exercise or pledge.

         (d) OTHER FORMS OF PAYMENT. The Committee may permit such other means
of tax withholding as it deems appropriate.

11. ASSIGNMENT OR TRANSFER OF AWARDS.
-------------------------------------

         (a) GENERAL. An Award granted under the Plan shall not be anticipated,
assigned, attached, garnished, optioned, transferred or made subject to any
creditor's process, whether voluntarily, involuntarily or by operation of law,
except as approved by the Committee. Notwithstanding the foregoing, ISOs may not
be transferable. Also notwithstanding the foregoing, while the Shares are
subject to California Corporations Code ss. 25102(o), (i) Offerees and Optionees
may not transfer their rights hereunder except by will, beneficiary designation
or the laws of descent and distribution, and (ii) any rights of repurchase in
favor of the Company shall take into account the provisions of Sections
260.140.41 or 260.140.42 of Title 10 of the California Code of Regulations, as
applicable.

         (b) TRUSTS. Neither this Section 11 nor any other provision of the Plan
shall preclude a Participant from transferring or assigning Restricted Shares to
(a) the trustee of a trust that is revocable by such Participant alone, both at
the time of the transfer or assignment and at all times thereafter prior to such
Participant's death, or (b) the trustee of any other trust to the extent
approved by the Committee in writing. A transfer or assignment of Restricted
Shares from such trustee to any other person than such Participant shall be
permitted only to the extent approved in advance by the Committee in writing,
and Restricted Shares held by such trustee shall be subject to all the
conditions and restrictions set forth in the Plan and in the applicable Stock
Award Agreement, as if such trustee were a party to such Agreement.

12. LEGAL REQUIREMENTS.
-----------------------

         Shares shall not be issued under the Plan unless the issuance and
delivery of such Shares complies with (or is exempt from) all applicable
requirements of law, including (without limitation) the Securities Act of 1933,
as amended, the rules and regulations promulgated thereunder, state securities
laws and regulations, and the regulations of any stock exchange on which the
Company's securities may then be listed.

13. NO EMPLOYMENT RIGHTS.
-------------------------

         No provision of the Plan, nor any right or Option granted under the
Plan, shall be construed to give any person any right to become, to be treated
as, or to remain an Employee. The Company and its Subsidiaries reserve the right
to terminate any person's Service at any time and for any reason.

14. DURATION AND AMENDMENTS.
----------------------------

         (a) TERM OF THE PLAN. The Plan, as set forth herein, shall become
effective on the date of its adoption by the Board of Directors, subject to the
approval of the Company's shareholders. In the event that the shareholders fail
to approve the Plan within twelve (12) months after its adoption by the Board of
Directors, any grants already made shall be null and void, and no additional
grants shall be made after such date. The Plan shall terminate automatically ten
(10) years after its adoption by the Board of Directors and may be terminated on
any earlier date pursuant to Subsection (b) below.

         (b) RIGHT TO AMEND OR TERMINATE THE PLAN. The Board of Directors may
amend the Plan at any time and from time to time. Rights and obligations under
any right or Option granted before amendment of the Plan shall not be materially
altered, or impaired adversely, by such amendment, except with consent of the
person to whom the right or Option was granted. An amendment of the Plan shall
be subject to the approval of the Company's shareholders only to the extent
required by applicable laws, regulations or rules including the rules of any
applicable exchange.

         (c) EFFECT OF AMENDMENT OR TERMINATION. No Shares shall be issued or
sold under the Plan after the termination thereof, except upon exercise of an
Option granted prior to such termination. The termination of the Plan, or any
amendment thereof, shall not affect any Shares previously issued or any Option
previously granted under the Plan.

                             2000 STOCK OPTION PLAN

                        INCENTIVE STOCK OPTION AGREEMENT

INCENTIVE STOCK OPTION              This Option is intended to be an incentive
                           stock option under section 422 of the Internal
                           Revenue Code and will be interpreted accordingly.

VESTING                             No Shares will vest until you have performed
                           _________ (____) months of Service from the
                           commencement of your employment with the Company.
                           Your Option shall vest as to ________ of the Shares
                           on the date _______ (____) months from the Vesting
                           Start Date as shown on the cover sheet. Thereafter,
                           Shares shall vest at the rate of _______ of the
                           Shares at the end of each full month thereafter.
                           After you have completed _________ (____) months of
                           Service, the number of Shares which vest under this
                           Option at the Exercise Price shall be equal to the
                           product of the number of full months of your
                           continuous employment with the Company ("Service")
                           (including any approved leaves of absence) from the
                           Vesting Start Date times the number of Shares covered
                           by this Option times ________. The resulting number
                           of Shares will be rounded to the nearest whole
                           number. No additional Shares will vest after your
                           Service has terminated for any reason.

                                    You should note that you may exercise the
                           Option prior to vesting. In that case, the Company
                           has a right to repurchase the unvested shares at the
                           original exercise price if you terminate employment
                           before vesting in all shares you purchased. Also, if
                           you exercise before vesting, you should consider
                           making an 83(b) election. Please see the attached Tax
                           Summary. THE 83(b) ELECTION MUST BE FILED WITHIN 30
                           DAYS OF THE DATE YOU EXERCISE.

TERM                                Your Option will expire in any event at the
                           close of business at Company headquarters on the day
                           before the tenth anniversary (fifth anniversary for a
                           10% owner) of the Date of Grant, as shown on the
                           cover sheet. (It will expire earlier if your Service
                           terminates, as described below.)

REGULAR TERMINATION                 If your Service terminates for any reason
                           except death, Disability or for "Cause," your Option
                           will expire at the close of business at Company
                           headquarters on the 30th day after your termination
                           date. During that 30-day period, you may exercise
                           that portion of your Option that was vested on your
                           termination date.

DEATH                               If you die while in Service with the
                           Company, your Option will expire at the close of
                           business at Company headquarters on the date six
                           months after the date of death. During that six-month
                           period, your estate or heirs may exercise that
                           portion of your Option that was vested on the date of
                           death.

DISABILITY                          If your Service terminates because of your
                           Disability, your Option will expire at the close of
                           business at Company headquarters on the date six
                           months after your termination date. (However, if your
                           Disability is not expected to result in death or to
                           last for a continuous period of at least 12 months,
                           your Option will be eligible for ISO tax treatment
                           only if it is exercised within three months following
                           the termination of your Service.) During that
                           six-month period, you may exercise that portion of
                           your Option that was vested on the date of your
                           Disability.

                                    "Disability" means that you are unable to
                           engage in any substantial gainful activity by reason
                           of any medically determinable physical or mental
                           impairment.

LEAVES OF ABSENCE                   For purposes of this Option, your Service
                           does not terminate when you go on a BONA FIDE leave
                           of absence that was approved by the Company in
                           writing, if the terms of the leave provide for
                           continued service crediting, or when continued
                           service crediting is required by applicable law.
                           However, your Service will be treated as terminating
                           30 days after you went on leave, unless your right to
                           return to active work is guaranteed by law or by a
                           contract. Your Service terminates in any event when
                           the approved leave ends unless you immediately return
                           to active work. The Company determines which leaves
                           count for this purpose, and when your Service
                           terminates for all purposes under the Plan. The
                           Company also determines the extent to which you may
                           exercise the vested portion of your Option during a
                           leave of absence.

NOTICE OF EXERCISE                  When you wish to exercise this Option, you
                           must execute EXHIBIT A (and, if exercise is prior to
                           vesting, you must also execute EXHIBITS B AND D).
                           Your exercise will be effective when it is received
                           by the Company. If someone else wants to exercise
                           this Option after your death, that person must prove
                           to the Company's satisfaction that he or she is
                           entitled to do so.

FORM OF PAYMENT                     When you submit EXHIBIT A, you must include
                           payment of the Exercise Price for the Shares you are
                           purchasing. Payment may be made in one (or a
                           combination) of the following forms at the discretion
                           of the committee:

                           o        Your personal check, a cashier's check or a
                                    money order.

                           o        Shares which you have owned for six months
                                    and which are surrendered to the Company.
                                    The value of the Shares, determined as of
                                    the effective date of the Option exercise,
                                    will be applied to the Exercise Price.

                           o        To the extent that a public market for the
                                    Shares exists as determined by the Company,
                                    by delivery (on a form prescribed by the
                                    Committee) of an irrevocable direction to a
                                    securities broker to sell Shares and to
                                    deliver all or part of the sale proceeds to
                                    the Company in payment of the aggregate
                                    Exercise Price.

                           o        Any other form of legal consideration
                                    approved by the Committee.

WITHHOLDING TAXES                   You will not be allowed to exercise this
                           Option unless you make acceptable arrangements to pay
                           any withholding or other taxes that may be due as a
                           result of the Option exercise or the sale of Shares
                           acquired upon exercise of this Option.

RESTRICTIONS ON RESALE              By signing this Agreement, you agree not to
                           exercise this Option or sell any Shares acquired upon
                           exercise of this Option at a time when applicable
                           laws, regulations or Company or underwriter trading
                           policies prohibit exercise or sale. In particular,
                           the Company shall have the right to designate one or
                           more periods of time, each of which shall not exceed
                           180 days in length, during which this Option shall
                           not be exercisable if the Company determines (in its
                           sole discretion) that such limitation on exercise
                           could in any way facilitate a lessening of any
                           restriction on transfer pursuant to the Securities
                           Act or any state securities laws with respect to any
                           issuance of securities by the Company, facilitate the
                           registration or qualification of any securities by

                                      -4-
<PAGE>

                           the Company under the Securities Act or any state
                           securities laws, or facilitate the perfection of any
                           exemption from the registration or qualification
                           requirements of the Securities Act or any applicable
                           state securities laws for the issuance or transfer of
                           any securities. Such limitation on exercise shall not
                           alter the vesting schedule set forth in this
                           Agreement other than to limit the periods during
                           which this Option shall be exercisable.

                           Furthermore, in respect of any underwritten public
                           offering by the Company, you agree that you will not
                           sell or otherwise transfer or dispose of any Shares
                           covered by this Option during a reasonable and
                           customary period of time as agreed to by the Company
                           and the underwriters, not to exceed the greater of
                           (a) 180 days following the effective date of the
                           registration statement of the Company filed under the
                           Securities Act in respect of such offering and (b)
                           such other period of time as agreed to by holders of
                           a majority of the then outstanding Shares. By signing
                           this Agreement you agree to execute and deliver such
                           other agreements as may be reasonably requested by
                           the Company or the underwriter which are consistent
                           with the foregoing or which are necessary to give
                           further effect thereto. The Company may impose
                           stop-transfer instructions with respect to the Shares
                           subject to the foregoing restriction until the end of
                           such period.

                           If the sale of Shares under the Plan is not
                           registered under the Securities Act of 1933, as
                           amended (the "Securities Act"), but an exemption is
                           available which requires an investment or other
                           representation, you shall represent and agree at the
                           time of exercise that the Shares being acquired upon
                           exercise of this Option are being acquired for
                           investment, and not with a view to the sale or
                           distribution thereof, and shall make such other
                           representations as are deemed necessary or
                           appropriate by the Company and its counsel.

THE COMPANY'S RIGHT OF              In the event that you propose to sell,
FIRST REFUSAL              pledge or otherwise transfer to a third party any
                           Shares acquired under this Agreement, or any interest
                           in such Shares, the Company shall have the "Right of
                           First Refusal" with respect to all (and not less than
                           all) of such Shares. If you desire to transfer Shares
                           acquired under this Agreement, you must give a
                           written "Transfer Notice" to the Company describing
                           fully the proposed transfer, including the number of
                           Shares proposed to be transferred, the proposed
                           transfer price and the name and address of the
                           proposed transferee. The Transfer Notice shall be
                           signed both by you and by the proposed transferee and
                           must constitute a binding commitment of both parties
                           to the transfer of the Shares.

                                    The Company and its assignees shall have the
                           right to purchase all, and not less than all, of the
                           Shares on the terms described in the Transfer Notice
                           (subject, however, to any change in such terms
                           permitted in the next paragraph) by delivery of a
                           Notice of Exercise of the Right of First Refusal
                           within 30 days after the date when the Transfer
                           Notice was received by the Company. The Company's
                           rights under this Subsection shall be freely
                           assignable, in whole or in part.

                                    If the Company fails to exercise its Right
                           of First Refusal within 30 days after the date when
                           it received the Transfer Notice, you may, not later
                           than 60 days following receipt of the Transfer Notice
                           by the Company, conclude a transfer of the Shares
                           subject to the Transfer Notice on the terms and
                           conditions described in the Transfer Notice. Any
                           proposed transfer on terms and conditions different
                           from those described in the Transfer Notice, as well
                           as any subsequent proposed transfer by you, shall
                           again be subject to the Right of First Refusal and
                           shall require compliance with the procedure described
                           in the paragraph above. If the Company exercises its
                           Right of First Refusal, you and the Company (or its
                           assignees) shall consummate the sale of the Shares on
                           the terms set forth in the Transfer Notice.

                                    The Company's Right of First Refusal shall
                           terminate upon the Company's initial public offering.

                                    The Company's Right of First Refusal shall
                           inure to the benefit of its successors and assigns
                           and shall be binding upon any transferee of the
                           Shares.

RIGHT OF REPURCHASE                 Following termination of your Service for
                           any reason, the Company shall have the right to
                           purchase all of those vested Shares that you have or
                           will acquire under this Option (unvested Shares which
                           have been exercised are subject to a Repurchase
                           Option set forth in EXHIBIT A). If the Company fails
                           to provide you with written notice of its intention
                           to purchase such Shares before or within 30 days of
                           the date the Company receives written notice from you
                           of your termination of Service, the Company's right
                           to purchase such Shares shall terminate. If the
                           Company exercises its right to purchase such Shares,
                           the Company will consummate the purchase of such
                           Shares within 60 days of the date of its written
                           notice to you. The purchase price for any Shares
                           repurchased shall be the higher of the fair market
                           value of the Shares on the date of purchase or the
                           aggregate Exercise Price for such Shares and shall be
                           paid in cash. The Company's right of repurchase shall
                           terminate in the event that Stock is listed on an

                           sole discretion.

TRANSFER OF OPTION                  Prior to your death, only you may exercise
                           this Option. You cannot transfer or assign this
                           Option. For instance, you may not sell this Option or
                           use it as security for a loan. If you attempt to do
                           any of these things, this Option will immediately
                           become invalid. You may, however, dispose of this
                           Option in your will.

                                    Regardless of any marital property
                           settlement agreement, the Company is not obligated to
                           honor a Notice of Exercise from your spouse or former
                           spouse, nor is the Company obligated to recognize
                           such individual's interest in your Option in any
                           other way.

RETENTION RIGHTS                    This Agreement does not give you the right
                           to be retained by the Company in any capacity. The
                           Company reserves the right to terminate your Service
                           at any time and for any reason.

SHAREHOLDER RIGHTS                  Neither you, nor your estate or heirs, have
                           any rights as a shareholder of the Company until a
                           certificate for the Shares acquired upon exercise of
                           this Option has been issued. No adjustments are made
                           for dividends or other rights if the applicable
                           record date occurs before your stock certificate is
                           issued, except as described in the Plan.

ADJUSTMENTS                         In the event of a stock split, a stock
                           dividend or a similar change in the Company's Stock,
                           the number of Shares covered by this Option and the
                           Exercise Price per share may be adjusted pursuant to
                           the Plan. Your Option shall be subject to the terms
                           of the agreement of merger, liquidation or
                           reorganization in the event the Company is subject to
                           such corporate activity.

LEGENDS                             All certificates representing the Shares
                           issued upon exercise of this Option shall, where
                           applicable, have endorsed thereon the following

NONSTATUTORY STOCK OPTION           This Option is not intended to be an
                           incentive stock option under section 422 of the
                           Internal Revenue Code and will be interpreted
                           accordingly.

VESTING                             No Shares will vest until you have performed
                           _______ (____) months of Service from the
                           commencement of your employment with the Company.
                           Your Option shall vest as to _______ of the Shares on
                           the date _______ (____) months from the Vesting Start
                           Date as shown on the cover sheet. Thereafter, Shares
                           shall vest at the rate of ________ of the Shares at
                           the end of each full month thereafter. After you have
                           completed ________ (____) months of Service, the
                           number of Shares which vest under this Option at the
                           Exercise Price shall be equal to the product of the
                           number of full months of your continuous employment
                           with the Company ("Service") (including any approved
                           leaves of absence) from the Vesting Start Date times
                           the number of Shares covered by this Option times
                           ________. The resulting number of Shares will be
                           rounded to the nearest whole number. No additional
                           Shares will vest after your Service has terminated
                           for any reason.

                                    You should note that you may exercise the
                           Option prior to vesting. In that case, the Company
                           has a right to repurchase the unvested shares at the
                           original exercise price if you terminate employment
                           before vesting in all shares you purchased. Also, if
                           you exercise before vesting, you should consider
                           making an 83(b) election. Please see the attached Tax
                           Summary. THE 83(b) ELECTION MUST BE FILED WITHIN 30
                           DAYS OF THE DATE YOU EXERCISE.

TERM                                Your Option will expire in any event at the
                           close of business at Company headquarters on the day
                           before the tenth anniversary (fifth anniversary for a
                           10% owner) of the Date of Grant, as shown on the
                           cover sheet. (It will expire earlier if your Service
                           terminates, as described below.)

REGULAR TERMINATION                 If your Service terminates for any reason
                           except death, Disability, or for "Cause" your Option
                           will expire at the close of business at Company
                           headquarters on the 30th day after your termination
                           date. During such 30-day period, you may exercise
                           that portion of your Option that was vested on your
                           termination date.

DEATH                               If you die while in Service with the
                           Company, your Option will expire at the close of
                           business at Company headquarters on the date six
                           months after the date of death. During that six-month
                           period, your estate or heirs may exercise that
                           portion of your Option that was vested on your date
                           of death.

DISABILITY                          If your Service terminates because of your
                           Disability, your Option will expire at the close of
                           business at Company headquarters on the date six
                           months after your termination date. During that
                           six-month period, you may exercise that portion of
                           your Option that was vested on your date of
                           Disability.

                                    "Disability" means that you are unable to
                           engage in any substantial gainful activity by reason
                           of any medically determinable physical or mental
                           impairment.

LEAVES OF ABSENCE                   For purposes of this Option, your Service
                           does not terminate when you go on a BONA FIDE leave
                           of absence that was approved by the Company in
                           writing, if the terms of the leave provide for
                           continued service crediting, or when continued
                           service crediting is required by applicable law.
                           However, your Service will be treated as terminating
                           30 days after you went on leave, unless your right to
                           return to work is guaranteed by law or by a contract.
                           Your service terminates in any event when the
                           approved leave ends unless you immediately return to
                           Service. The Company determines which leaves count
                           for this purpose, and when your Service terminates
                           for all purposes under the Plan. The Company also
                           determines the extent to which you may exercise the
                           vested portion of your Option during a leave of
                           absence.

NOTICE OF EXERCISE                  When you wish to exercise this Option, you
                           must execute EXHIBIT A (and if exercise is prior to
                           vesting you must also execute EXHIBITS B AND D). Your
                           Exercise will be effective when it is received by the
                           Company. If someone else wants to exercise this
                           Option after your death, that person must prove to
                           the Company's satisfaction that he or she is entitled
                           to do so.

FORM OF PAYMENT                     When you submit EXHIBIT A, you must include
                           payment of the Exercise Price for the Shares you are
                           purchasing. Payment may be made in one (or a
                           combination) of the following forms at the discretion
                           of the committee:

                           o        Your personal check, a cashier's check or a
                                    money order.

                           o        Shares which you have owned for six months
                                    and which are surrendered to the Company.
                                    The value of the Shares, determined as of
                                    the effective date of the Option exercise,
                                    will be applied to the Exercise Price.

                           o        To the extent that a public market for the
                                    Shares exists as determined by the Company,
                                    by delivery (on a form prescribed by the
                                    Committee) of an irrevocable direction to a
                                    securities broker to sell Shares and to
                                    deliver all or part of the sale proceeds to
                                    the Company in payment of the aggregate
                                    Exercise Price.

                           o        Any other form of legal consideration
                                    approved by the Committee.

WITHHOLDING TAXES                   You will not be allowed to exercise this
                           Option unless you make acceptable arrangements to pay
                           any withholding or other taxes that may be due as a
                           result of the Option exercise or the sale of Shares
                           acquired upon exercise of this Option.

RESTRICTIONS ON RESALE              By signing this Agreement, you agree not to
                           exercise this Option or sell any Shares acquired upon
                           exercise of this Option at a time when applicable
                           laws, regulations or Company or underwriter trading
                           policies prohibit exercise or sale. In particular,
                           the Company shall have the right to designate one or
                           more periods of time, each of which shall not exceed
                           180 days in length, during which this Option shall
                           not be exercisable if the Company determines (in its
                           sole discretion) that such limitation on exercise
                           could in any way facilitate a lessening of any
                           restriction on transfer pursuant to the Securities
                           Act or any state securities laws with respect to any
                           issuance of securities by the Company, facilitate the
                           registration or qualification of any securities by
                           the Company under the Securities Act or any state
                           securities laws, or facilitate the perfection of any
                           exemption from the registration or qualification
                           requirements of the Securities Act or any applicable
                           state securities laws for the issuance or transfer of
                           any securities. Such limitation on exercise shall not
                           alter the vesting schedule set forth in this
                           Agreement other than to limit the periods during
                           which this Option shall be exercisable.

                           Furthermore, in respect of any underwritten public
                           offering by the Company, you agree that you will not
                           sell or otherwise transfer or dispose of any Shares
                           covered by this Option during a reasonable and
                           customary period of time as agreed to by the Company
                           and the underwriters, not to exceed the greater of
                           (a) 180 days following the effective date of the
                           registration statement of the Company filed under the
                           Securities Act in respect of such offering and (b)
                           such other period of time as agreed to by holders of
                           a majority of the then outstanding Shares. By signing
                           this Agreement you agree to execute and deliver such
                           other agreements as may be reasonably requested by
                           the Company or the underwriter which are consistent
                           with the foregoing or which are necessary to give
                           further effect thereto. The Company may impose
                           stop-transfer instructions with respect to the Shares
                           subject to the foregoing restriction until the end of
                           such period.

                           If the sale of Shares under the Plan is not
                           registered under the Securities Act of 1933, as
                           amended (the "Securities Act"), but an exemption is
                           available which requires an investment or other
                           representation, you shall represent and agree at the
                           time of exercise that the Shares being acquired upon
                           exercise of this Option are being acquired for
                           investment, and not with a view to the sale or
                           distribution thereof, and shall make such other
                           representations as are deemed necessary or
                           appropriate by the Company and its counsel.

THE COMPANY'S RIGHT OF              In the event that you propose to sell,
FIRST REFUSAL              pledge or otherwise transfer to a third party any
                           Shares acquired under this Agreement, or any interest
                           in such Shares, the Company shall have the "Right of
                           First Refusal" with respect to all (and not less than
                           all) of such Shares. If you desire to transfer Shares
                           acquired under this Agreement, you must give a
                           written "Transfer Notice" to the Company describing
                           fully the proposed transfer, including the number of
                           Shares proposed to be transferred, the proposed
                           transfer price and the name and address of the
                           proposed transferee. The Transfer Notice shall be
                           signed both by you and by the proposed transferee and
                           must constitute a binding commitment of both parties
                           to the transfer of the Shares.

                                    The Company and its assignees shall have the
                           right to purchase all, and not less than all, of the
                           Shares on the terms described in the Transfer Notice
                           (subject, however, to any change in such terms
                           permitted in the next paragraph) by delivery of a
                           notice of exercise of the Right of First Refusal
                           within 30 days after the date when the Transfer
                           Notice was received by the Company.

                                    The Company's rights under this Subsection
                           shall be freely assignable, in whole or in part.

                                    If the Company fails to exercise its Right
                           of First Refusal within 30 days after the date when
                           it received the Transfer Notice, you may, not later
                           than 60 days following receipt of the Transfer Notice
                           by the Company, conclude a transfer of the Shares
                           subject to the Transfer Notice on the terms and
                           conditions described in the Transfer Notice. Any
                           proposed transfer on terms and conditions different
                           from those described in the Transfer Notice, as well
                           as any subsequent proposed transfer by you, shall
                           again be subject to the Right of First Refusal and
                           shall require compliance with the procedure described
                           in the paragraph above. If the Company exercises its
                           Right of First Refusal, you and the Company (or its
                           assignees) shall consummate the sale of the Shares on
                           the terms set forth in the Transfer Notice.

                                    The Company's Right of First Refusal shall
                           terminate upon the Company's initial public offering.

                                    The Company's Right of First Refusal shall
                           inure to the benefit of its successors and assigns
                           and shall be binding upon any transferee of the
                           Shares.

RIGHT OF REPURCHASE                 Following termination of your Service for
                           any reason, the Company shall have the right to
                           purchase all of those vested Shares that you have or
                           will acquire under this Option (unvested Shares which
                           have been exercised are subject to a Repurchase
                           Option set forth in EXHIBIT A). If the Company fails
                           to provide you with written notice of its intention
                           to purchase such Shares before or within 30 days of
                           the date the Company receives written notice from you
                           of your termination of Service, the Company's right
                           to purchase such Shares shall terminate. If the
                           Company exercises its right to purchase such Shares,
                           the Company will consummate the purchase of such
                           Shares within 60 days of the date of its written
                           notice to you. The purchase price for any Shares
                           repurchased shall be the higher of the fair market
                           value of the Shares on the date of purchase or the
                           aggregate Exercise Price for such Shares and shall be
                           paid in cash. The Company's right of repurchase shall
                           terminate in the event that Stock is listed on an
                           established stock exchange or is quoted regularly on
                           the Nasdaq National Market. The fair market value
                           shall be determined by the Board of Directors in its
                           sole discretion.

TRANSFER OF OPTION                  Prior to your death, only you may exercise
                           this Option. You cannot transfer or assign this
                           Option. For instance, you may not sell this Option or
                           use it as security for a loan. If you attempt to do
                           any of these things, this Option will immediately
                           become invalid. You may, however, dispose of this
                           Option in your will.

                                    Regardless of any marital property
                           settlement agreement, the Company is not obligated to
                           honor a Notice of Exercise from your spouse or former
                           spouse, nor is the Company obligated to recognize
                           such individual's interest in your Option in any
                           other way.

RETENTION RIGHTS                    This Agreement does not give you the right
                           to be retained by the Company in any capacity. The
                           Company reserves the right to terminate your Service
                           at any time and for any reason.

SHAREHOLDER RIGHTS                  Neither you, nor your estate or heirs, have
