             LMKI, INC. AMENDED AND RESTATED 1999 STOCK OPTION PLAN
             ------------------------------------------------------

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

         The purpose of the Amended and Restated 1999 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.

         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

         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

         Market or the Nasdaq National Market;

                  (3) If the Shares were traded on a stock exchange on the date

financial statements need not be audited.

ITEM 4. ELIGIBILITY.

         (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 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.

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

         (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-


         (b) DURATION OF OFFERS. Any right to acquire Shares under the Plan

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.

                                      -8-


         (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.

ITEM 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.

                                      -9-


ITEM 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

         (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.

ITEM 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

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.

ITEM 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

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.

                                      -12-


         (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.

         (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.

ITEM 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.

                                      -13-


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

         Shares shall not be issued under the Plan unless the issuance and

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.

ITEM 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

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

         (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

                   AMENDED AND RESTATED 1999 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.

                                      -16-


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.

                                      -17-


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

                                      -18-


                           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.

                                      -19-


                                    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
                           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
                           legends:

                       NONSTATUTORY STOCK OPTION AGREEMENT

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.)

                                      -2-


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.

                                      -3-


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.

                                      -4-


                           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.

                                      -5-


                                    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.

                                      -6-


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
